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
