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.

4.1: Introduction to Rational Functions - Mathematics LibreTextsA rational function is a function which is the ratio of polynomial functions. Said differently, r is a rational function if it is of the form. r(x) = p(x) q(x), where p and q are polynomial functions. a. a According to this definition, all polynomial functions are also rational functions. (Take q(x) = 1).

5.6 Rational Functions – College AlgebraA rational function is a function that can be written as the quotient of two polynomial functions. Many real-world problems require us to find the ratio of two polynomial functions. Problems involving rates and concentrations often involve rational functions.

Rational Function – Definition, Equations, and Examples - Math MonksThe word ‘ratio’ is the root of the term ‘rational’. Thus, a rational function is the ratio of two polynomial functions where the denominator is never 0. A 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.

Study Guide - Rational Functions - SymbolabRational Functions. Suppose we know that the cost of making a product is dependent on the number of items, x, produced. This is given by the equation C\left (x\right)=15,000x - 0.1 {x}^ {2}+1000 C (x) = 15,000x −0.1x2 + 1000. If we want to know the average cost for producing x items, we would divide the cost function by the number of items, x.
