Answer:

2

Explanation:

Given:

The interval, x = -2 to x = 0.

Required:

Average rate of change from x = -2 to x = 0.

SOLUTION:

From the graph,

If x = -2, f(-2) = 0.

If x = 0, f(0) = 4

Average rate of change =
(f(b) - f(a))/(b - a)

Where,


a = -2, f(a) = 0


b = 0, f(b) = 4

Plug in the values into the formula:


= (4 - 0)/(0 -(-2))


= (4)/(2) = 2

Average rate of change from x = -2 to x = 0 is 2.
