Start with the given function.
Replace f(x) with y
Switch x and y. The goal is to solve for y
Subtract 4 from both sides.
Divide both sides by -3.
Reduce
So the inverse function is =\frac{-x+4}{3})
-----------------------------------------
Start with the inverse function.
=\frac{-(-41)+4}{3})
Plug in
=\frac{41+4}{3})
Negate -41 to get 41
=\frac{45}{3})
Add
=15)
Divide
So the answer is
