Given:

The table of values.

To find:

The average rate of change for the given function from x = −1 to x = 2.

Solution:

From the given table it is clear that y=-3 at x=-1 and y=3 at x=2.

Formula for average rate of change is


m=(y_2-y_1)/(x_2-x_1)

Using the above formula, the average rate of change for the given function from x = −1 to x = 2 is


m=(3-(-3))/(2-(-1))


m=(3+3)/(2+1)


m=(6)/(3)


m=2

Therefore, the correct option is D.
