    All real numbers except x = 0.

    If you meant g(x) = (x + 7)/(x^2 - 36) or x + 7/(x^2 - 36), then all real numbers except x = 6 and x = -6.

    First responder's answer is wrong no matter how your question is interpreted. The interpretation you intended was probably

    g(x) = (x+7)/(x^2 - 36), whose domain is (-inf,-6)U(-6,6)U(6,+inf).

    The literal interpretation of what you typed is

    g(x) = x + (7/x^2) - 36, whose domain is (-inf,0)U(0,+inf).

    The reason why you needed to put in parentheses is that you eliminated a horizontal fraction-bar, which is itself a symbol of inclusion.

    (- infinity, -7) (-7, infinity)
