Graphing Exponential Functions: Key Patterns and Techniques

The video tutorial explores exponential functions, starting with basic graphing techniques by plotting points for functions like f(x) = 2^x. It discusses the behavior of exponential graphs with positive and negative exponents, highlighting the concept of asymptotes. The tutorial then examines the impact of changing the base of exponential functions, showing how larger bases lead to faster growth. It also covers fractional bases and how they result in graph flipping. The video concludes with a preview of more advanced graphing techniques.
