Exponential Functions and Growth Concepts

The lesson covers modeling exponential growth and decay using functions. It explains how to use a graphing calculator to graph these functions, describes the domain, range, and asymptotes, and provides examples of exponential growth and decay. The lesson concludes with a summary and assignment details.
