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:
4^(5+2) + 7 - (4^(-3+2) +7)
--------------------------------------
5 +3
Step-by-step 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
