### In case you didn't listen in class...

Alright. Today in class we went over last night's homework and answered any questions that you had (that is if you weren't there or just didn't pay attention). Last night's homework was the first two sides of the packet about graphing Logs. The post below will have what you need. Tonight's homework is to finish the packet. As Anthony FAILED to mention yesterday, Mrs. Prior handed out the Midterm Review Packet that we all know and love. So, if you didn't get one, ask.

*What is a composite function? How do we create a composition of two or more functions? What do we know about the domain of composite functions? How do we decompose a function? And 6 more....*

Classwork: Today we went over the 10 essential questions that summarize what we have learned so far(Mrs. Prior took a picture of them). Specifically, we spent more time reviewing how to restrict the domain of the original function so that the inverse would be a function.

Homework: Study for the quiz on Wednesday! It would be helpful to review the essential questions, Glencoe homework assignments, and the rule of four packets. Also, all of the notes we have taken during class. Good luck studying!

**December 6, 2012**

Today in class we received

*Contemporary Mathematics in Context*textbook (blue). Everyone needs to return the orange books at some point. Then, we worked on Investigations 1 and 2 in the blue book (pg 143-149) and tried answering the essential questions written on the board.

**Essential Questions:**

- What is the definition of inverse function?
- What is the relationship between the domains and ranges of inverse functions?
- What is the relationship between the graphs of inverse functions?
- How do we verify algebraically that two functions are inverses?
- When does a function have an inverse function?
- How do we algebraically find the inverse of a function?

**Homework:**GPC assignment # 4 (pg 71 #46, 48, 50, 52; pg 70 #14, 16, 18, 28, 30) due tomorrow

Re-works for Function Families and Vertical Transformations Quiz due Monday

**Reminder:**Quiz on Monday## Wednesday, December 5, 2012

Today in class 12/5 we talked about the definition of inverse functions.
We also discussed the factors that have to be true for two functions to
be inverse. We discussed and did practice problems on how to find and
verify/ prove inverse functions. We went over why some functions must
have restrictions put on them in order to find the inverse functions. If
a function doesn't pass the horizontal line test it must have
restrictions on it's domain before the inverse function can be found.
There was no homework tonight.

EQ: What is a

*composition*of functions? How do we compose two or more functions and__simplify__the result?
In-Class: We did a Mad Minutes quiz. Mrs. Prior checked the HW (GPC#1) and then we went over the HW answers. We did more practice composing and simplifying functions.

Mrs. Prior handed out the new investigation in a packet.

Homework: Inv. 2 #4-6 (in new packet)

## Wednesday, November 14, 2012

In-Class: We did an activity that will continue tomorrow in class, where we had to identify equations from graphs of different parent functions. These graphs included both horizontal AND vertical translations.

Homework: Pages 10-15 in the PINK Packet due tomorrow!

### Tuesday, November 13, 2012

In class today, we were given a new equation that was ±Af[C(x±D)]±B. Each group was given a colored sheet of paper that was considered "part" of the equation and had to write down what it meant. Part of what we learned was about horizontal transformations. Pictures to come soon, but for the part [C(x was the id o<c<1, the parent function would be stretched horizontally, if c>1, than the parent function is compressed horizontally. However, in most cases except for trig functions, the C value can be used as an A value. The ±D)] part is when it is being added, the graph translates to the left. If it's being subtracted, the graph shifts right.

For homework we were given a pink packet with graphs of certain function families and transformations to fill out. Pages 4-9 are due tomorrow.

__Essential Question:__What are the effects of A and D on the graph and table of +/- A(F(x))+D?

__In Class:__Today we did an activity of posing in the shape of specific functions, and talked about certain variables that would translate, reflect, compress or stretch parent functions. A packet, "Practice with Vertical Transformation on Function Families", was given out to, well, practice graphing functions of the form +/- A(F(x))+D.

__HW:__None for tomorrow, though test corrections are due Friday. May be a good idea to do a couple graphs in the packet.

__In Class__: Today in class we worked on piece wise graphs and graphing them when we are given equations. Then we put the graphs on the board and discussed them. Also, we did the same thing with floor and ceiling graphs.

__HW:__Finish the piece wise packet that she gave us at the end of class for Friday and also the writing assignment is due Friday.

## Tuesday, October 23, 2012

__In Class:__Today in class, we worked on our packet with practice problems for the function families. Practice problems inluded solving linear, exponentail, and power model euquations. Mrs. Prior also passed back a few papers from a while ago, like the unit circle quiz filling in coordinates.

__HW__: Finish the packet except for nmber one on the last page. This means #1-3, #1-6,and #8. You don't need to do the step function on the last page!

## Monday, October 22, 2012

__In Class__: For the first half of the class we peer edited our writing assignments. Mrs. Prior stressed the idea that communicating our thinking and ideas is the most important, not necessarily if you arrive at the correct answer. She gave us a hard copy of the rubric on colored paper. The second of the class we went over problem #5 on page 426. We discussed how to find volume of an irregular shape if you are given the area of the base or height. With problem 5 part d, the volume and area of the base were given, so we were able to find the base.

__HW:__The writing assignment is due on Friday and MUST be typed. We were also given a packet and Mrs.Prior told us to start it and we will have time to work on it tomorrow in class. You should be able to do the kidney bean pool problem.

### Thursday, October 18, 2012

__In Class:__We did a quick quiz on labeling the function families of graphs. Also, we worked on our writing assignment with our partners that chose to describe the same senario for last night's homework. Remember for the equation part that Mrs. Prior doesn't care if it is right; she just wants to see your effort and frame of thought.

__HW:__Work on the writing assignment draft that is due Monday.

**Field trip people-**Work on the writing assignment along with pg. 434 #1 and #2 in the thin orange book.

__Essential Question:__What type or types of situations can be modeled by the various function families?

__In-Class:__Mrs.Prior is back! At the beginning of class we took a mad minute quiz. We also did an activity with different graphs and had to form a group with people that had the same function families. Then we tried to pick a problem that would best represent the graphs we were given. Some people had no problems, some people had one or two. We added these graphs and problems to the posters of the different function families. Go math!

__HW:__Jot down some ideas about ONE problem out of the four given on the assignment paper. Be prepared for a quick quiz tomorrow on function families. Four graphs will be given and then we have to decide what family each belongs to.

## Monday, October 15, 2012

__Essential Question:__How do we identify which family a function belongs to if we are given a ...graph? ...equation? ...description? ...table?

__In-class:__Mrs.Prior was absent today, and we had a substitute. We were given the entire class to work on #2-6 on p.424-427 in the orange books we got last week (

*Contemporary Mathematics in Context*).

__HW:__Finish #2-6 on p.424-427.

__Essential Question__: How do we convert between angle measures?

__Classwork__: Did another Mad Minutes quiz, talked about, explained and came up with examples of co-terminal angles (equations- x+360°n or x+n2Ï€ where is x the given degree and n is the number of full rotations [must be a whole number]). We labeled radians for all labeled angles on the unit sheet as well. (Trick to remember: All 45° degree related measure are 1/4Ï€ greater than the last. All others go up by 1/6Ï€.) We also went over the homework (assignment #3) in class.

__Homework__: Assignment #4 (due 9/13)

Writing Assignment (due 9/14)

## Tuesday, September 11, 2012

Class: Took a quick quiz on x and y-cordinates and thier relations to circle degrees when on an x-y plane and right triangles. Then we tried to convert radians to degrees and radians to degrees. There are many different way to do this. Such as using a proportion, dimensional anaylsis, or multiplying. We now know that 1 radian=180 degrees/pi and 1 degree=pi/180 degrees.

Homework:Assignment #3(due tomorrow) and the online assignment (due friday)

## Monday, September 10, 2012

Essential Question:What is a radian?

Class: New seats, blog assignments, online assignment, continued going over radian worksheet (millimeter beads), radian is another way to measure angles (bigger than degrees), 2pi is the amount of radians in a circle

Homework:Come up with radian measures for all special angles (on unit circle...30, 45, 60, 90, 120, 135, 150, 180, 210, 225, 240, 270, 300, 315, 330, and 360), Quick Quiz tomorrow on x and y-coordinates and degrees in the Unit Circle
