Unit 4: Exponential & Logarithmic Functions (BI Chapter 6), Day 6: Logarithms & Logarithmic Functions, Day 2

Learning Objectives:

You will learn about logarithms, the inverse function for exponentials.
You will be able to define and evaluate logarithms.
You will learn the essential characteristics of the graph of a logarithmic function and relate them to exponential functions.

Guided Notes:

6.3.1 Introduction to Logarithms

Solutions: 6.3.1 Solutions to examples from the powerpoint.

6.5.1 Properties of Logarithms

"When the base matches the base, the answer is the exponent!"
Finding inverse functions... Swap & Solve!

If you were absent, look at the guided notes, and check out the videos in the linked resources below.

Homework/Practice: HW #4.6, (Big Ideas 6.3, Day 2) p. 315 #35-50; 55 & 56. Don't forget to write the problems!
