Graphing Rational Functions

  • If the numerator and denominator have a common binomial factor, the graph will have a hole at the point where this factor is 0. If the denominator has a binomial factor that is not in the numerator, the graph will have a vertical asymptote at the point where this factor is 0.

  • The graph of a rational function often has a horizontal asymptote.
