what is the average rate of change from x = -4 to x = 4 for the graphed exponential equation:

-5/8

Step-by-step explanation:

Rate of change will be given by the gradient of the graph between the given intervals

For x = -4 we have the point, (-4,  0)

For x = 4 we have the point, (4, -5)

Gradient = change in y /change in x

               = (0 - -5)/(-4 - 4)

                = 5/-8

                = -5/8

The average rate of change = -5/8

x=4
