Lesson Summary:
In this lesson, you will learn how to identify different models by graph, including linear, quadratic, exponential, logistic, and other models. By understanding the shape of these models, you will be able to determine which one is the best fit for your data. The video demonstrates how to transform a base function, such as the identity function for linear models, to fit a given set of data. The lessons are easy to follow and include interactive elements that allow you to practice what you have learned.
Lesson Description:
Given a Cartesian plot be able to identify whether it is linear, quadratic, exponential, logistic, or other.

Staff Review
It is common to have a set of data and want to model the data with the best possible function. To do this, you must know which function would fit the data best. This and the next lesson, along with the problem set and solutions, will help you perfect this art.
