x f(x)
_______
−1 3
0 0
1 -1
2 0
3 27


What is the average rate of change from x = −1 to x = 2?
A. −3
B. −1
C. 1
D. 24

Answer 1

-1 hope this helpz man

Answer 2

The average rate of change from
`x=-1` to
`x=2` is
`-1`

Step-by-step explanation

The average rate of change from
`x=-1` to
`x=2`

`=(f(2)-f(-1))/(2-(-1))`

From the table,

`f(2)=0` and
`f(-1)=3`.

So we substitute in to the above expression for average rate of change.

`Average\:Rate\:of\:Change=(0-3)/(2+1)`

`=(-3)/(3)`

`=\-1`

The correct answer is B
