Exponential and Linear Models Assessment

The video tutorial explains how to compare linear, quadratic, and exponential models. It covers how to identify these models by graphing data and analyzing patterns. The tutorial also demonstrates writing equations for each model type and applying them to real-world scenarios, such as predicting population growth.
