## What is an example of a rational function?

Examples of Rational Functions

The function R(x) = (x^2 + 4x – 1) / (3x^2 – 9x + 2) is a rational function since the numerator x^2 + 4x – 1 is a polynomial and the denominator 3x^2 – 9x + 2 is also a polynomial.

## What is rational equation in math?

A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials … These fractions may be on one or both sides of the equation. A common way to solve these equations is to reduce the fractions to a common denominator and then solve the equality of the numerators.

## What is rational equation and example?

Equations that contain rational expressions are called rational equations. For example 2x+14=7x 2 x + 1 4 = 7 x is a rational equation. Rational equations can be useful for representing real-life situations and for finding answers to real problems.

## How do you solve a radical equation?

To solve a radical equation:
1. Isolate the radical expression involving the variable. …
2. Raise both sides of the equation to the index of the radical.
3. If there is still a radical equation repeat steps 1 and 2 otherwise solve the resulting equation and check the answer in the original equation.

## What is a rational exponent give an example?

Square roots are most often written using a radical sign like this √4 . But there is another way to represent them. You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. For example √4 can be written as 412.

## What is a rational solution?

## What are 5 examples of rational equation?

Solving Rational Equations
• 4/x + 5/2 = -11/x.
• 5x/(x – 2) = 7 + 10/(x – 2)
• (3x – 2)/(x – 2) = 6/(x2 – 4) + 1.
• 2/(x2 – x) = 1/(x – 1)
• 3/(x + 2) = 6/(x – 1)

## How do you know if the equation is a rational equation?

When we have an equation where the variable is in the denominator of a quotient that’s a rational equation. We can solve it by multiplying both sides by the denominator but we have to look out for extraneous solutions in the process.
