Question

What is the average rate of change of f(x) from x=0 to x=4?

F(x)=x^2-8x-2
Enter your answer in the box.

Answer 1

Average rate of change is -4

Explanation:

Step One: Evaluate the Function for A and B

f(0) = -2

f(4) = -18

Step Two: Use the Average Rate of Change Formula

(f(b) - f(a))/(b-a)

(-18 - (-2)) divided by (4-0) equals -16/4

-16/4= -4
