# 5.1 Exponential Functions

## Assignment 5.1:

• p.334: #1,2,3-11 odd, 12-16 all, 17-31 odd, 43,45,46,49-52 all

# Video 5: The number e

## Assignment 5.2:

• p.342: #11-20 all. (I know that seems like a lot, but it should go fast…unless you really need the practice),23,25,26,27 (feel free to write some code that fills out the tables for you), 43,45,49,51,55,61

# Video 7: The graph of a logarithmic function

## Assignment 5.3:

• p.356; #1-4 all
• p.356; Make sure you know how to do these (Optional inverse function review): #6,7,8
• p.357; 9,11
• Do these without a calculator: 15-18 all
• p.357; 19,21,23,24,25,43,45,47,49,51,65
• Honors: Write a program that fills out the charts for #68, also #69 (no code for this one)

## (Open note) Possible quiz topics for wednesday:

• Basic questions about functions and their inverses. You may want to go back to the unit on functions for review.
• What does it mean for a function to be one to one?
• Why does the horizontal line test work?
• Explain how video 5 defines the number e.
• Give a verbal description of the meaning of the log of a number with a given base.
• Convert equations from logarithmic form to exponential form and visa versa.
• Sketch the graphs of exponential and logarithmic functions on the same axes. Describe their domains and ranges.

# Video 10: Properties of logarithms examples.

## Assignment 5.4:

• p.368; #1-17 odd, 21-27 odd
• p.369; #51,52,51,55 (I know this seems out of order)
• p.369; #31,33 (You might want to do 51-55 first, to get a little practice with change of base.)
• p.369; #43,45,47
• p.369; #62 (If you are working in a group, make sure that everyone comes up with their own examples.)
• p.369; #63
