Answer:
-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
