Prove that linear functions grow by equal differences over equal intervals - F-LE.1

In this lesson, you will learn to prove that linear functions grow by equal differences over equal intervals by showing algebraically that the difference does not depend on the particular x-coordinates involved.

In this lesson, you will learn to prove exponential functions grow by equal factors over equal intervals by showing algebraically that the difference does not depend on the particular x-coordinates involved.

This video explains how to determine if a function given as a table is a linear function, exponential function, or neither.
