Mathematics Success Tips: Asymptotes

*Warning* The information given here is not given in technical mathematical definitions and is not the complete

knowledge that you need. Instead it attempts to give a basic understanding of the concept using non-rigorous

terms.

An asymptote is a line that a graph gets closer and closer to, but never touches or crosses it. There are

three main types of asymptotes that functions may have: horizontal, vertical, or oblique. Using the

conditions that follow, you may be able to determine where the asymptotes exist.

Horizontal Asymptotes

o If the denominator has a higher degree than the numerator, then y=0 is your horizontal asymptote plus the constant.

o If the degrees of both the numerator and denominator are the same, then the ratio of the lead coefficients of the two highest degrees will be the horizontal asymptote plus the constant.

Vertical Asymptotes

o Set the denominator of your function equal to zero and solve. The value(s) you get will be vertical asymptote(s).

Oblique or Slant Asymptotes

o Slant asymptotes only exist when the numerator has a degree EXACTLY one greater than the degree of the denominator. Use polynomial division (either long division or synthetic division) or factor to find the quotient. The quotient will be your slant asymptote (you can ignore the remainder).

o Don’t forget that a special case exists when the numerator and denominator share a common factor. In which case the remainder will be zero, the slant asymptote WILL be

the graph, and there will be a hole or holes (points of discontinuity) where the domain is restricted.
