Describe The Domain And Range Of A Rational Function

Rational expressions high school 9th grade.

Describe the domain and range of a rational function. Recall that the domain of a function is the set of possible input values x values of the function. Step by step mathematics algebra rational functions domain and range of a function domain and range of the rational function domain and range. Learn how to find the domain of rational functions.

A vertical asymptote represents a value at which a rational function is undefined so that value is not in the domain of the function. In algebra when we deal with points on a graph you may be asked to find its domain and range. Let us again consider the parent function f x 1 x.

Let s learn what each of these mean. The vertical asymptotes of a rational function will occur where the denominator of the function is equal to zero and the numerator is not zero. Range y domain y 1 therefore the range of y is.

In general to find the domain of a rational function we need to determine which inputs would cause division by zero. In that case we have to sketch the graph of the rational function using vertical asymptote horizontal asymptote and table of values as given below.
