Rational functions can never intersect vertical asymptotes.

Work Step by Step

Vertical asymptotes will occur when the value of the denominator is equal to zero. Because we cannot divide by 0, the value of the function will always be undefined at the vertical asymptote. Consequently, it would not make sense for a function to cross the vertical asymptote, for the function is undefined for this value of x.
