graphing functions...please help

[roxstar1]

sketch the graph of the equation. Look for extrema, intercepts, symmetry, and assymptotes as necessary.

y = x/((x^2)-4)

I am especially having difficulty finding the "symmetry" of this graph

If \(\displaystyle f(x)\,=\,\frac{x}{x^{2}-4}\), investigate f(x) vs. -f(-x).
