Understanding Exponential Functions

The video tutorial explains how to complete tables using given equations and a calculator. It covers entering equations, setting up the table, and using the table feature to determine y values. The tutorial highlights the importance of rounding correctly and provides examples of exponential decay and growth. It concludes with an analysis of graphs for both types of exponential functions.

What is the primary purpose of using a calculator in this tutorial?

• To complete tables with given equations

• To solve linear equations

• To draw geometric shapes

• To calculate integrals
