Question

Which expression below gives the average rate of change of the function h(x) = 4^x+2 + 7 on the interval –3 ≤ x ≤ 5?

Answer 1

Answer: i got the answer c. Good luck!

Answer 2

4^(5+2) + 7 - (4^(-3+2) +7)

--------------------------------------

5 +3

Explanation:

The average rate of change is given by

h(5) - h(-3)

---------------

5 - -3

h(5) - h(-3)

---------------

5 +3

h(5) = 4^(5+2) + 7

h(-3) = 4^(-3+2) +7

4^(5+2) + 7 - (4^(-3+2) +7)

---------------

5 +3
