Rational Function – Definition, Equations, and Examples - Math MonksA function of a real variable x, say f (x), is a rational function if it can be represented as: f (x) = p (x) q (x), here p (x), q (x) are polynomials in x with q (x) ≠ 0. For example, f (x) = 3 x + 5 x 2 − x − 2, is a rational function where the denominator x 2 – x – 2 ≠ 0.

Rational function - WikipediaIn mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials. The coefficients of the polynomials need not be rational numbers ; they may be taken in any field K .

3.9: Rational Functions - Mathematics LibreTextsConstruct Graphs of Rational Functions. In Example \(\PageIndex{10}\), we see that the numerator of a rational function reveals the x-intercepts of the graph, whereas the denominator reveals the vertical asymptotes of the graph. As with polynomials, factors of the numerator may have integer powers greater than one. Fortunately, the effect on ...

Study Guide - Rational Functions - SymbolabKey Points. A rational function is any function which can be written as the ratio of two polynomial functions, where the polynomial in the denominator is not equal to zero. The domain of [latex]f (x) = \frac {P (x)} {Q (x)} [/latex] is the set of all points [latex]x [/latex] for which the denominator [latex]Q (x) [/latex] is not zero.
