IN CLASS:  Today we took notes on Section 4.3 - The Natural Exponential Function.

HOMEWORK:  None

January 11, 2010

Monday, January 11

IN CLASS:  Today we talked about applications of exponential functions.

HOMEWORK:  Finish worksheet from class.  I will collect these tomorrow.  Study for quiz!

UPCOMING:  Quiz TOMORROW on Sections 4.1 and 4.2.  You should be able to:
- Determine if a function is one-to-one. (Set f(a)=f(b) or use horizontal line test)
- Find the inverse of a function. (Switch x and y, solve for y, and rename.)
- Solve equations involving exponentials.  (Get same base on both sides.)
- Solve application of exponential word problems.  I will give you the formulas, but you should know what all of the variables in them mean.
