Graphing Exponential Parent Functions

This video tutorial introduces the concept of exponential functions, focusing on graphing the functions 2^x and (1/2)^x. It explains how to set up a table of values to plot these functions and discusses the domain and range of exponential functions. The video also covers the concept of asymptotes, particularly the horizontal asymptote, and how it relates to the graph of an exponential function. By the end of the video, viewers will understand how to graph exponential functions and determine their domain and range.
