Question

What is the average rate of change for this quadratic function for the interval from x =3 to x = 5

(PLEASE HELP NEED ANSWER ASAP)

Answer 1

A. -8

Step-by-step explanation:

Answer 2

A

Explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

`(f(b)-f(a))/(b-a)`

here [ a, b [ = [ 3, 5 ]

From the table

f(b) = f(5) = - 26

f(a) = f(3) = - 10

Hence average rate of change

=
`(-26-(-10))/(5-3)` =
`(-16)/(2)` = - 8 → A
