the first thing you should do is produce a graph of the question. If you have a graphing calculator use that. Desmos gives terrific graphs (see below) which you can study to answer your question. The only answer that makes any sense is that after the discontinuity at x = 1 or x = - 1 the y value approaches 0. It is written something like 1<x<infinity x is contained in the reals, the graph approaches 0.
