Answer:

or in radians:

Step-by-step explanation:
From the way you wrote, you want to solve the equation
for
, or in radians 

<u>Square both sides</u>



In the Unit Circle, considering one revolution (interval
),
the values where
are in Quadrant II and III.
Once

The values where
are 120º and 240º.
With this inverse functiion, you would want to replace f(x) with y for now.
so new equation
y = 1/4^x - 12
then change positions of y and x
x = 1/4^y - 12
Then try to get Y by itself
x + 12 = 1/4^y
So then use Logarithm
Log Base_ 1/4 _ (x+12) = y
OK, this written in numbers is

But, fractions can not divide. So we need to multiply one by the reciprocal of the other. The reciprocal of a fraction is itself flipped upside down. For example, the reciprocal of 1/2 would be 2/1.
So, we will multiply 3/2 by 4/1. We know how to do this, it is simply 3/2*4=12/2=6.
So, the answer is n = 6. That would be answer c, because 6 is between 5 and 7.
