Answer:
ave rate of change = (-6)^(2+2) +3 - (-6)^(-1+2) +3
---------------------------------------------
2+1
Explanation:
To find the average rate of change
ave rate of change = f(x2) - f(x1)
----------------
x2-x1
We know that x2 = 2 and x1 = -1
ave rate of change = f(2) - f(-1)
----------------
2--1
ave rate of change = (-6)^(2+2) +3 - (-6)^(-1+2) +3
---------------------------------------------
2+1
