Question

Given the function h(x)=-x^2+10x+32h(x)=−x
2
+10x+32, determine the average rate of change of the function over the interval 3\le x \le 113≤x≤11.

Answer 1

Welcome to QC (:

There's an easy way to do this but not sure if you've learned derivatives, have you?

Answer 2

Stop being formal

Answer 3

I haven't

Answer 4

Fudge

Okay then just substitute 3 and 11 in for x

\(h(x)=-(3)^2+10(3)+32\) and

\(h(x)=-(11)^2+10(11)+32\)

Answer 5

o.0

Answer 6

Do you know how to solve it?

\(-(3)^2+10(3)+32\)

\(-(11)^2+10(11)+32\)

Answer 7

56

Answer 8

120

Answer 9

7/15?

Answer 10

Basically like last time (:

\(\dfrac{120-56}{11-3}\)

Answer 11

Ocho

Answer 12
