Explanation:
We know that the average rate of change of a function that contains the points (a,b) to (c,d) is given by :-

Then, the average rate of change of a function that contains the points (-2,3) and (2,5)will be:-

Hence, the average rate of change of a function that contains the points (-2,3) and (2,5). = 0.5
