7.1: Introducing Rational Functions - Mathematics LibreTextsDefinition: Rational Functions. A rational function is a function that can be written as a quotient of two polynomial functions. In symbols, the function \[f(x)=\frac{a_{0}+a_{1} x+a_{2} x^{2}+\cdots+a_{n} x^{n}}{b_{0}+b_{1} x+b_{2} x^{2}+\cdots+b_{m} x^{m}} \nonumber \] is called a rational function.

Study Guide - Rational Functions - SymbolabAny function of one variable, [latex]x[/latex], is called a rational function if, and only if, it can be written in the form: [latex-display]f(x) = \dfrac{P(x)}{Q(x)}[/latex-display] where [latex]P[/latex] and [latex]Q[/latex] are polynomial functions of [latex]x[/latex] and [latex]Q(x) \neq 0[/latex]. Note that every polynomial function is a ...

Rational Functions - Wolfram|AlphaRational functions are functions that involve a quotient of polynomial expressions. While rationals share many properties with polynomials, there are some unique aspects that arise due to the division of polynomials, such as asymptotes and singularities. Solve rational equations, find roots, graph, convert to alternate forms, simplify and ...
