Question

Given the function h(x)=-x²+4x+12, determine the average rate of change of the function over the interval -1≤x≤8

Answer 1

Explanation:

the average rate of change is

(h(interval end) - h(interval begin)) /

(interval end - interval begin)

in our case this is

(h(8) - h(-1)) / (8 - -1) = (108 - 9) / 9 = 99/9 = 11/1 = 11
