Exploring Features of Exponential Functions

Mrs. Rio's video tutorial covers the features of exponential functions, including graphing them, analyzing their tables and graphs, and understanding their domain, range, and asymptotes. The video also explains how to calculate the average rate of change and plot points on a graph, emphasizing the importance of the y-intercept. The tutorial uses a calculator to demonstrate these concepts, providing a comprehensive understanding of exponential functions.
