    I would say that the range of this graph is (-infinity,infinity) and the domain is (-infinity,-3]U[3, infinity).

    By setting y=0 and solving for the value of x, which is 3 and -3, explains why the range is what it is. The graph is not defined between (-3, 3).

    I think this is correct, but I may be wrong on the domain, but I'm pretty sure it's right.

    Actually, I don't think the graph is defined at y=0, this means that the range is (-infinity,0)U(0,infinity). with a domain that is (-infinity, -3)U(3,infinity).
