Question

How to find the average rate of change of a function

Answer 1

ANSWER

Average Rate of Change

$= \frac{f(b) - f(a)}{b - a}$

EXPLANATION

To find the average rate of change of y=f(x) from x=a to x=b means finding the slope of the secant line joining the points

(a,f(a)) and (b,f(b))

The slope of the secant line joining these points is

$= \frac{f(b) - f(a)}{b - a}$

This gives the average rate of change of the function.
