## DarkBlueChocobo one year ago Help with inverses

1. DarkBlueChocobo

So I am stumped on this one problem. $f(x)=\frac{ 2x }{ x-1 } x \neq1$

2. DarkBlueChocobo

So we are dealing with restricted domain. I am having issues trying to get the inverse I get to $x=\frac{ 2y }{ y-1 }$

3. DarkBlueChocobo

we could multiply out y-1 and get $x(y-1)=2y$
