Answer:
-4
Step-by-step explanation:
The average rate of change of a function f(x) between two points x = a and x=b is given by,

This can be understood with a simpler example, the straight line.
In this case, the rate of change of the 'function' is given by the slope,
;
being two points on the straight line.
So, for the given problem,
a = -2
b = 2
Hence, average rate of change of
