    The domain is actually \mathbf{R}.

    If you were to graph this, you would have a horizontal graph y = -6 ending at x = -3, a horizontal graph y = 6 starting at x = 3, and joined with a "diagonal" line y = 2x.

    So for what values of y is this function defined?

    Also did you mean horizontal graph y = -6 starting at x = -3 ?
