Find the average rate of change of g(x)=2x2-8x from x=2 to x=5

Answer 1

The average rate of change is 20.

Explanation:

To find the answer, plug in the 2 and 5 for x.

g(2) = 2(2)^2 - 8(2)

g(2) = 16 - 16

g(2) = 0

g(5) = 2(5)^2 - 8(5)

g(5) = 100 - 40

g(5) = 60

g(5)-g(2)/5-2 = the average rate of change

60/3=20
