Answer:

Step-by-step explanation:
Okay, to do this we must understand what parallel means.
parallel means that that one line will NEVER touch the other. In order for this to happen they must be increasing (or decreasing) by the SAME rate. I.e the slope of your line must be the same as the lin in question thus our equation looks like,
.
Now lets find
.
To do this, plug the point (3,6) into the equation
6=4(3)+C
6=12+C
-6=C
Thus now that we know C, our equaiton is

The file includes the input of your equation, comment if the equation you input is a mistake.
Find the invers of f(x)
f(x) = 2x - 6
y = 2x - 6
y + 6 = 2x
2x = y + 6
x = (y + 6)/2
f⁻¹(x) = (x + 6)/2
Solve f⁻¹(x) for x = 2
Subtitute x with 2
f⁻¹(x) = (x + 6)/2
f⁻¹(x) = (2 + 6)/2
f⁻¹(x) = 8/2
f⁻¹(x) = 4
The answer is 4
We make sample calculations per month, assuming that you visit the gym x times per month.
(1) $39.95 per month
(2) total = $14.95 + $2.95x
If we have the value of x, it is much easier for us to determine the answer by just substituting the value of x and solve. Whichever gives the lower cost will be our answer.
