In class: Today we went over certain parts of last night's homework on the board and solidified our understanding of how to rewrite exponential functions with different bases. We also learned about natural log and the significance of e as a number and as a base in an exponential function. When e to the power of x is graphed, it has the slope of 1 at the point where it meets the line y=x.

Homework: A worksheet with more compounding interest and exponential function practice.

Essential Questions: How do we express exponential function in equivalent forms with different bases? How do we use exponential functions to solve problems about compounding interest?

Reminders: There will be a test on this material sometime next week!

In class: On Monday and today we took notes about bases,compounding and continuous compounding. We learnt about e means and limit notation.
Homework: Pg.451 #2 and Pg.452 #3 (Both of these are modeling problems and remember to do this because it will effect whether are not you can complete a rework for a test or quiz)! Just in case you didn't do Monday's homework it was a compounding worksheet.
Essential Questions: How do we express exponential functions in equivalent forms with different bases?
How do we use exponential functions to solve problems about compounding interest?

Today we worked in the new blue book number 1,2,4,5 on page 438. Our homework is number 6 on page 440 and the OYO.

January 24, 2013

Today was midterm review day! We got back our midterms.  We took two surveys in the computer lab. No homework except try to bring in your blue book tommorrow we're getting a new one. First day of Semester two tommorrow!

In class today (Tuesday) we continued with the log station activity.

The homework for tonight is to continue doing the midterm packet. The writing assignment is also due tomorrow. The big quiz on logs is Friday.

Friday, January 4, 2013

In Class: Today we did a mad minute at the beginning of class. We also learned how to solve three different types of log functions. The first just uses the definition of a log, the second uses the properties of logs and the definition, and the third has logs on both sides.

HW: Do GPC#12 and work on the midterm-review packet.

In Class: We had a Mad Minutes quiz at the beginning of class, then we went over the answers together. Afterward, we fixed a misprint in our midterm packet on #21: the function should be f(x)=log(base 3)(3x-6)+2 instead of 10^(x+1)=29. We got the rest of class to work on the Partner Writing Assignment, which is due next Thursday, January 10. (We got to choose our partners.) Each pair should turn in one final draft, and Mrs. Prior would like it if we sent them to her email so she can grade them on her iPad.

Homework: Do GPC #11, work on the midterm packet as well as on the Partner Writing Assignment, and don't forget that the individual Online Writing Assignment is due tonight by 11:59 pm!

Reminders: There is a big logs quiz next Friday, January 11! Our midterm exam is the Friday after that, January 18.

Essential Questions:

• What is the definition of a logarithm?
• How do we rewrite exponential equations?
• What are the properties of logs and how do we use them (Exponent, Product, and Quotient)?
• How do we change the base of log equations?
• How do we graph basic (ex. log base 2 of x) and transformed (ex. log base 2 of (x+3)) log functions?
• How do we solve exponential equations using logs?
• How do we solve log equations?

Examples of solving exponential equations using logs (from class 1/2/13):

First post of 2013!

In Class: We got our schedule for January and important dates to come ahead which included the early release on the 8th, assignments, the quiz and our midterm schedule. We worked on six equations with x as the exponent and as the base which we then had to solve those algebraically WITHOUT A CALCULATOR for x.

Homework: Online Writing Assignment due tomorrow (scroll down to the Dec.17 post), GPC# 10, and maybe even attempt to start the midterm review packet!
