    the first 3 have something in common (look at the degrees of the denominator)

    since they all involve subtraction, this means that that each of the first 3 have 2 vertical asymptotes

    but what's given is just one vertical asymptote

    since the other 3 have 2 vertical asymptotes?

    it says that there is exactly 1 vert asymptote, but the first 3 have 2 vert asymptotes, so the first 3 must be ruled out because of this discrepancy

    it may be possible that one of the 2 vertical asymptotes are given, its not written that ' there is exactly 1 vert asymptote'

    plus domain does not contain -3 , but domain of 4th contains -3

    true, i guess the domain paints a more definitive picture

    so looking at the domain, which does not contain +3 or -3, the denominator will be x^2-9

    so my answer is C?
