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.
