Find a formula f-1(x). Give the domain of f-1, including any restrictions "inherited" from f
So one of my problem is f(x)=3x-6
But I'm kind of confused on how to start off
At first I thought it was like having the equation all go to the power of -1
So I got y=(1/3)x-(1/6)
But in the answer book it says: y=(1/3)x + 2
Finding the inverse function (not the "reciprocal" which is 1/f) for any function means swapping x and y and then solving for y. It is, strictly speaking, the swapping of x to y that gives the inverse function but we always want a function written in the form y= f(x) so we always want to solve for y.
