My last question really need
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.

a. -2
b. -1
c. 1
d. 2

Average rate of change is just the slope between the points

the average rate of change from x=-1 to x=2 is
(f(2)-f(-1))/(2-(-1))

given
f(2)=3
f(-1)=-3

slope=(3-(-3))/(2-(-1))=(3+3)/(2+1)=6/3=2
average rate of change is 2

D is answer
