Exponential and Linear Functions Concepts

This video tutorial covers exponential functions, starting with a comparison to linear functions. It explains exponential growth, how to evaluate exponential functions using order of operations, and criteria for identifying them. The tutorial also includes graphing exponential functions and interpreting the graphs, using examples to illustrate key points.
