Like it’s cousin the improper fraction (where the numerator is larger than the denominator), a rational function is improper if the degree of the numerator is bigger than the degree of the denominator. It’s very similar to the idea of an proper fraction in algebra, where the numerator is smaller than the denominator. The degree of P(x) is less than the degree of Q(x).What is a Proper Rational Function?Ī proper rational function is a ratio of functions where the degree of the numerator (the top number in a fraction) is less than the degree of the denominator (the bottom number).
