if the domain of f(x) is (-1,1) then what is the domain of f((x+1)/(x-1))?

i don't even know how to start this problem. all i know is that x cannot be equal to 1.

What is this? A rational function?

'Cause the way I find is that you take the bottom part and whatever turns out to be zero is what makes the domain...

Did you need to rewrite it in a different notation?

$\displaystyle (-\infty, 1) \cup (1, \infty)$ - Sep 30th 2009, 10:38 PMmr fantastic
