# Understanding Rational Functions And Graphs

Rational functions are a type of mathematical functions that are made up of two variables. The variables can be polynomials, fractions, or any other mathematical expression. This type of function is often used to map out relationships between two variables. It is also used to represent data in graphs, which can be helpful in understanding mathematical concepts. In this article, we will discuss which of the following rational functions is graphed below.

## What is a Rational Function?

A rational function is a mathematical expression that contains two variables, usually represented by polynomials. The variables are related in a way that produces a graph with some distinct points. These points, when plotted, form a line or curve. The line or curve is known as a rational graph. The shape of the graph is determined by the values of the two variables. This type of function is also sometimes referred to as a rational equation.

## Types of Rational Functions

There are several different types of rational functions. The most common type is the linear rational function. This type of function is made up of two linear equations. The graph of this type of function will be a straight line. Other types of rational functions include quadratic rational functions, which have a graph shaped like a parabola, and cubic rational functions, which have a graph shaped like a cube.

## How to Graph a Rational Function

In order to graph a rational function, you first need to find the values of the two variables. This can be done by using a graphing calculator or by using a graphing software program. Once the values of the two variables are known, you can then plot the points on a graph. The points should be connected to form a line or curve. The shape of the graph will depend on the type of rational function it is.

## Which of the Following Rational Functions is Graphed Below?

The graph below shows a quadratic rational function. This type of function is made up of two polynomials and produces a graph that looks like a parabola. The graph can be used to determine the values of the two variables in the function. Knowing these values will help you determine which of the following rational functions is graphed below.

## Conclusion

Understanding rational functions and graphs can be a useful skill in understanding mathematical concepts. Knowing which of the following rational functions is graphed below can help you understand the relationship between the two variables in the function. With the help of a graphing calculator or graphing software program, you can easily plot the points and determine the type of rational function that is graphed below.
