Graphing Basic Exponential Functions

The video tutorial explains the graph of exponential functions, highlighting the difference between growth and decay. It covers the basic form y = b^x, where the y-intercept is typically (0,1), and discusses how transformations affect the anchor point. The tutorial provides examples of graphing exponential functions, including those with negative bases and bases less than one, and explains the concept of horizontal asymptotes. It concludes with a discussion on graph transformations and reflections.
