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 
Answer:
scale factor = 
Step-by-step explanation:
the scale factor is the ratio of corrresponding sides. image to original.
scale factor =
=
= 
M< means to measure so I would measure
Personally I would say C because when you take good notes you can go over what you don’t remember. You can also use your notes as a study guide.
