Exploring Graphs of Exponential Functions

This video tutorial covers graphing exponential functions, starting with a review of input/output tables. It demonstrates graphing y = 2^x and compares linear and exponential growth. The tutorial also explores graphing with fractional bases, such as f(x) = 4*(1/2)^x, highlighting exponential decay. The video concludes with a practice example for viewers to try on their own.
