Estimating derivatives using data

Estimating derivatives using data

Author: Keely Baker
Description:

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.
