1. Review: exponential growth and Decay functions

2. In this lesson, you will review how to write an exponential growth and decay function modeling a percent of increase situation or decrease situation by interpreting the percent of increase as a growth factor or percent of decrease as a decay factor.

3. Review: exponential growth functions Exponential growth happens by repeated multiplication by the same number.
