Answer:
Option C is correct.

Step-by-step explanation:
Let x be the distance cover by Michelle
Given:
A circle diameter is 3 miles.
And Michelle biked around the trail 4 times.
We know that
The circumference of a circle.
circumference =
----------(1)
where 
miles
Put
and r value in equation 1.


The circumference of a circle is 9.42 miles.
And Michelle biked 4 times, that is equal to 4
circumference.

.
That is equal to 38 miles.
Therefore, Michelle biked around 4 trail is 38 miles.
Plug in -3 for x into the equation.
(1/4)^-3
And solve
(1/4)^-3 = 64
Answer:
3
Step-by-step explanation:

If
is 3, then



Both
and
equal 3. So, the value of
must be 3 for the function to have the same coordinate for
and
.
