This video tutorial covers graphing exponential functions, focusing on key features such as the y-intercept, asymptote, domain, and range. It introduces the concept of asymptotes, particularly horizontal asymptotes, and provides examples of graphing exponential growth and decay using a calculator. The video concludes with a summary of key takeaways and instructions for practice problems.
