Answer:
The answer is A.
Step-by-step explanation:
Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.
![y=12x-20\\ y+20=12x\\ x=\frac{y+20}{12}](https://tex.z-dn.net/?f=y%3D12x-20%5C%5C%20y%2B20%3D12x%5C%5C%20x%3D%5Cfrac%7By%2B20%7D%7B12%7D)
Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).
f-1(x) = (x+20)/12
