What Is The Domain Of A Rational Parent Function

The domain of a rational function consists of all the real numbers x except those for which the denominator is 0.

What is the domain of a rational parent function. Solve the equation found in step 1. Here are the steps required for finding the domain of a rational function. To find which numbers make the fraction undefined create an equation where the denominator is not equal to zero. A rational function is simply a fraction and in a fraction the denominator cannot equal zero because it would be undefined.

This time we will tackle how to find the domain and range of more interesting functions namely radical functions and rational functions we will take a look at two 2 examples on how to find the domain and range of radical functions and also two 2 examples of rational functions. Solve to find the x values that cause the denominator to equal zero. In rational functions p x and q x are both polynomials and q x cannot equal 0. Rational functions follow the form.

A rational function is a function made up of a ratio of two polynomials. In the parent function f x 1 x both the x and y axes are asymptotes. Given a rational function find the domain. The domain of a rational function includes all real numbers except those that cause the denominator to equal zero.

Write your answer using. To find these x values to be excluded from the domain of a rational function equate the denominator to zero and solve for x. The parent function of rational functions is. A rational function in the form y a x b c has a vertical asymptote at the excluded value or x b and a horizontal asymptote at y c.

The graph of the parent function will get closer and closer to but never touches the asymptotes.
