Rational functions
Asymptotes, holes and domain — where a fraction of polynomials blows up.
A rational function is one polynomial over another. Where the denominator is zero the function has a vertical asymptote (or a hole, if the factor cancels); the degrees decide the horizontal or slant asymptote. Cancelling common factors first is what separates the two cases.
