Answer:
and 
Step-by-step explanation:
The function is given as 
<em>to find inverse, we follow the steps shown below:</em>
<em>1. write "y" in place of "f(x)"</em>
<em>2. interchange "x" and "y"</em>
<em>3. solve for the new "y"</em>
<em>4. replace y with f^-1(x)</em>
<em />
Let's do this:
These 2 are the inverse functions.

Answer:
200 miles
Step-by-step explanation:
First, set up the equations.
plan 1: initial fee of $55.96, $0.12 per mile
plan 2: initial fee of $63.96, $0.08 per mile
We want to know at what distance will the cost be the same. So, set the equations equal to each other.
0.12x + 55.96 = 0.08x + 63.96
Combine the variables.
0.04x + 55.96 = 63.96
Combine the constants.
0.04x = 8
Divide by 0.04 to isolate x.
x = 200 miles
Check by plugging x back into each equation.
y = 0.12(200) + 55.96
y = 24 + 55.96
y = $79.96
y = 0.08(200) + 63.96
y = 16 + 63.96
y = $79.96
You are correct!
