Section 2-4

This document contains information about exponential functions including: 1. It provides examples of calculating values of exponential functions for integer values of n from -10 to 10 and using those results to calculate 322.4. 2. It discusses the characteristics of exponential growth and decay functions based on whether the base b is greater than, less than, or equal to 1. 3. It provides two examples of exponential growth and decay functions modeling population changes over time and compares the graphs of three exponential functions.
