I don't know if you want the whole x+2 on the bottom or not, but I will put it on the bottom for now.
Replace x with (3+h)
f(3+h)=1/[(3+h)+2]
Now if it's supposed to be JUST x in the denominator...
Replace x with (3+h)
f(3+h)=1/(3+h)+2

He will use 33 containers because 9 goes into 296 32.8 times but you cant have .8 of a container so you round it up to 33
Answer:

Step-by-step explanation:
To solve this, we are using the average rate of change formula:

where
is the average rate of change
is the first point
is the second point
is the function evaluated at the first point
is the function evaluated at the second point
We want to know the average rate of change of the function
form x = -3 to x = 0, so our first point is -3 and our second point is 0. In other words,
and
.
Replacing values







We can conclude that the average rate of change of the exponential equation form x = -3 to x = 0 is
