Use the table below to answer this question:   x y −1 -3 0 -1 2 3 find the average rate of change for the given function from x = −1 to x = 2.

In the interval from x=-1 to x=2, x increases by 3. In that same interval, y increases by 6 from -3 to +3. The average rate of change is
.. average rate of change = (increase in y)/(increase in x) = 6/3 = 2

The average rate of change is 2 over the given interval.
