What is a Rational Function? A rational function is a function that is the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as f (x) = p (x)/q (x), where p …

Aug 3, 2023 · Like polynomial functions, a rational function has zeros or roots, the points where the graph crosses the x-axis, or f (x) = 0. In a rational function, they are the zeros of the numerator, and …

In 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.

A rational function is a function made up of a ratio of two polynomials. Rational functions follow the form: In rational functions, P (x) and Q (x) are both polynomials, and Q (x) cannot equal 0. The parent …

Rational functions or algebraic fractions, are functions that are fractions because they have a numerator and denominator. Rational functions are expressed as the ratio of two polynomials such that the …

What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph by connecting …

Sep 14, 2025 · A 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.

Illustrated definition of Rational Function: A function that is the ratio of two polynomials. It is Rational because one is divided by the other, like a...

A rational function is a function that can be expressed as the ratio of two polynomials, P (x) and Q (x), where Q (x) ≠ 0. It's written as f (x) = P (x) / Q (x).

Rational Functions are just a ratio of two polynomials (expression with constants and/or variables), and are typically thought of as having at least one variable in the denominator (which can never be 0).
