It's hard to help you without know what you already understand. And we can't know that if you don't show what you have tried yourself. Do you understand what "f(x)= x/(1- x^2)" means? (And notice that "x^2" is a little clearer than "1- x2".) Do you know what "domain" and "range" mean? Do you know what f^-1 means? Do you know "go f^-1" means? I am sure you do know what at least some of those mean but it is impossible to be sure or know what you do understand without seeing what you have attempted.
