Question 1000725: We are doing inverses in class and I am stuck on this one problem. Can you help me?
It says,"for the given function f(x), find f^-1(x)
f(x)=x/3 I know I'm supposed to replace f(x) with y and then interchange x and y to get x=y/3 but now i'm stuck. Am I even on the right track? Please help.
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
Yes, you are on the right track.
Once you do that you again solve for y and get
y = 3x
and then substitute f^-1(x) for y.
