ANSWER
Average Rate of Change
[tex] = \frac{f(b) - f(a)}{b - a} [/tex]
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
[tex] = \frac{f(b) - f(a)}{b - a} [/tex]
This gives the average rate of change of the function.
