Question

The average rate of change on the interval -3 <= x <= 4 is?

f(-3 ) = 45
f(4 ) = 31

Answer 1

\[\frac{f(4)-f(-3)}{4-(-3)}\]

Answer 2

7?

Answer 3

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

Answer 4

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

Answer 5

or is just 7?

Answer 6

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

Answer 7

ooh ok

Answer 8

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

Answer 9

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