Question

HELP ASAP!! What is the average rate of change between x = -3 and x = 4 for the equation y = 8x2?

Answer 1

8 is the average rate of change

Explanation:

Plugin -3 and 4 in for x.

y = 8(-3)^2

y = 72

y = 8(4)^2

y = 128

128-72/4-(-3) = the average rate of change

56/7=8

Answer 2

`x=-3\\y=8(-3)^2\\y=8(9)\\y=72`

`x=4\\y=8(4)^2\\y=8(16)\\y=128`

128-72=56

average rate of change is 56

Plz let me know if im right
