Suppose the the limit as x approaches 6 to the left equals infinity. What conclusion can be made about the graph of y = f (x)?
there is a horizontal asymptote at y = 6
there is a horizontal asymptote at y = 6
there is a vertical asymptote at x = 6
there is a vertical asymptote at x = 6

we know x is not going to infinity, so the asymptote must be vertical.
