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.

Today we took another awesome mad minutes and went over questions in our previous homework together. Today’s homework is to complete questions 1 through 4 in the packet
Calendar for January 2013, including exam schedule:

Today in class we learned about logarithms and how a log. function is the inverse of an exponential function.  The homework is GPC number 7.  p.178 #1-11,15,17,22,24 and p.178 #48,50-52

Today in class, we took a quiz on composite functions and inverse functions.

Homework: NONE.

Essential Questions: 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

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.
Yesterday 12/4 in class we went over the homework from Monday and went over how to decompose functions. We also made a table about what Opposite, Reciprocal, Additive Inverse, Multiplicative Inverse, and Inverse functions. We also went over what Identity was. Our homework was in the Glencoe Precalculus book assignment 3.
