Answer 4

The average rate of change of function over the interval [a,b] can be found as follows:
average rate = [f(b)-f(a)]/(b-a).
Your given table is for y, so substitute y(x) for f(x).

Answer 5

what is f(x) when x is -3 ?

Answer 6

-3x

Answer 7

use your table. look for -3 in the x column. read f(x)

Answer 8

So -3 6 right thnx

Answer 9

-3 is the answer

Answer 10

that is the first step. Now find f(x) when x is 4

Answer 11

4f :/

Answer 12

?

Answer 13

f(x) when x is 4
do the same thing you did to find f(x) when x was -3

Answer 14

look in the table in the x column for 4
then read f(x)
