Lesson Summary:
In this lesson, we learn how to evaluate non-linear models both numerically and symbolically. The video focuses on the three model functions: quadratic, exponential, and logistic, and discusses how to find their respective parameters before evaluating them. The lesson uses practical examples and refers back to earlier objectives to teach a step-by-step approach to evaluating non-linear models. Solver is also introduced as a tool to solve for unknown variables in non-linear models.
Lesson Description:
Be able to evaluate (i.e. find an output given an input) and of the three model functions both numerically and symbolically.

Staff Review
This lesson shows the three non-linear models that are covered in this series (quadratic, logistic, and exponential) and explains how to do a regression and evaluate a quadratic function. A TI graphing calculator is used to help model and evaluate the function. This is a great tutorial.
