Understanding Exponential Functions

The video tutorial explains how to match equations to graphs by identifying exponential functions. It covers the concept of initial value, which is the y-intercept, and distinguishes between exponential growth and decay based on the base value. The tutorial guides viewers through matching equations to graphs by analyzing the initial value and the base, explaining that a base between 0 and 1 indicates decay, while a base greater than 1 indicates growth. The video concludes with examples of matching equations to specific graphs based on these characteristics.

What does the initial value 'A' represent in an exponential function?
