Identifying Linear, Quadratic, and Exponential Models

The video tutorial explains how to choose between linear, quadratic, and exponential models to represent data sets. It covers the characteristics of each model, how to use graphs to identify them, and how to analyze data numerically. The tutorial also discusses the importance of common differences and ratios in determining the type of model and provides steps to write and verify equations that best fit the data.
