The student will study a table of data from a function and determine the approximate rate of change at a point.

Using the information given in a table, we can estimate the instantaneous rate of change at a point by using the slope formula learned in Algebra. This is because the slope of a function *is* the average rate of change and at some point on a continuous interval, the average rate of change is equal to the instantaneous rate of change.

Tutorial

This video shows how to find average rates of change.
