Identifying Function Characteristics

This video tutorial explains how to differentiate between linear, quadratic, and exponential functions using finite differences. It covers identifying these functions by their equations and analyzing tables of values to classify them. The video demonstrates using first differences for linear functions, second differences for quadratic functions, and ratios for exponential functions. It also includes graphing examples to visualize each function type.
