What Are Rational Functions? - House of Math

Rational functions are fractions where both the numerator and the denominator are polynomial functions. Learn why hyperbolas are rational functions.

Rational Function | Formula, Properties & Examples - Lesson

Rational functions are a broad class of functions with no universal formula. However, all rational functions are quotients of polynomial functions.
