Best ResponseYou've already chosen the best response.0Okay....so the inverse of a function is a function such that \[f(f ^{1}(x))=1\] Right?

Best ResponseYou've already chosen the best response.0I thought it would be such that f(f^1(x)) = x Im probably wrong...

Best ResponseYou've already chosen the best response.0No you are right. :) It's been a little while since I've done inverses.

Best ResponseYou've already chosen the best response.0Okay, to find the inverse we can solve y=f(x) for x: y=(14x)/(4x) (4x)*y=14x 4yxy+4x1=0 4y1xy+4x=0 4y1x(y+4)=0 x(y+4)=14y x=(14y)/(y+4) x=(4y1)/y+4 = f^(1)(x) Check my arithmetic and algebra cause I get really sloppy!!
