The procedure for finding the inverse is as follows, I will workout the question and explain the procedure at the same time:
f ( x ) = 4 x + 17 x
First step: change f(x) to y
y = 4 x + 17 x
Second step: swap x and y
x = 4 y + 17 y
Third step: Re-solve for y
After further solving, we find that y = x 4 x 2 + 17
Fourth step: replace y with y = f 1 ( x )
f 1 ( x ) = x 4 x 2 + 17 This is the inverse.
