The video introduces exponential functions, highlighting their differences from linear functions. It covers evaluating exponential functions, calculating average rates of change, and graphing them using a calculator. The behavior of exponential functions is explained based on their base values, distinguishing between growth and decay. The video also demonstrates how to identify exponential functions from tables and concludes with real-world applications.

What distinguishes exponential functions from linear functions?

• Exponential functions have constant rates of change.

• Exponential functions graph as straight lines.
