## anonymous 4 years ago The average rate of change on the interval -3 <= x <= 4 is? f(-3 ) = 45 f(4 ) = 31

1. myininaya

$\frac{f(4)-f(-3)}{4-(-3)}$

2. anonymous

7?

3. myininaya

formula for slope is also the formula for average rate of change

4. anonymous

do you plug in the 45 and 31 for the f(x)s?

5. anonymous

or is just 7?

6. myininaya

you are given f(4) which is 31 and f(-3) which is 45

7. anonymous

ooh ok

8. anonymous

so the equation should look like this 31-(45)

9. myininaya

the expression is $\frac{31-45}{4-(-3)}$

10. anonymous

-14/7 is the anwser?

11. myininaya

which can be simplified to ??

12. anonymous

2

13. myininaya

14. anonymous

-2 then

15. myininaya
