The graph of g(x) is symmetric with respect to the origin

The graph of g(x) is symmetric with respect to the origin if

$g(-x)=-g(x)$

that's if g(x) is an odd function , then it is:

$**g(-x)** =((-x)^2-1)/(-x)=-(x^2-1)/x **=-g(x)**$

graph{(x^2-1)/x [-5, 5, -5, 5]}

How do you determine whether the graph of g(x)=(x^2-1)/xg(x)=(x^2-1)/x is symmetric with respect to the origin?
