What is the average rate of change of f(x)=1/4x^2-4 over the interval from 0 to 3?

1/4

Step-by-step explanation:

To find the average rate of change we find

f(3) -f(0)

3-0

We need to find f(3) = 1/4 (3)^2 -4 = 1/4 (9) -4 = 9/4 -4 = -7/4

                            f(0) = 1/4 (0)^2 - 4 = -4

f(3) -f(0)

3-0

-7/4 - (-4)

3-0

-7/4 +4

3-0

-7/4 +4

3-0

-7/4 +16/4
