# How do you write domain with excluded values?

## How do I find the domain and excluded values of a rational function?

The domain of a rational function consists of all the real numbers x except those for which the denominator is 0 . To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x .

## How do you write domain with excluded values?

Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator. f(x) x / (x – 3). The denominator has only one zero, x 3. So the domain of f is the set of all numbers other than 3.

## How do you find the excluded values of a rational function?

To find the excluded value in the domain of the function, equate the denominator to zero and solve for x . So, the domain of the function is set of real numbers except u22123 . The range of the function is same as the domain of the inverse function.

## How do you find the excluded domain?

Finding Excluded Values of Rational Expressions Factor the denominator of the rational expression. Find the value that makes each factor equal zero. These are excluded values of the domain of the rational expression.

## What are considered excluded values from the domain?

Steps for Simplifying a Rational Expression Determine the domain. The excluded values are those values for the variable that result in the expression having a denominator of 0

## How do you write domain and range?

Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

## How do you find the excluded values of a rational expression?

Finding Excluded Values of Rational Expressions Factor the denominator of the rational expression. Find the value that makes each factor equal zero. These are excluded values of the domain of the rational expression.

## How can you determine the excluded values in a product or quotient of two rational expressions?

a product or quotient of two rational expressions? You can multiply and divide rational expressions in much the same way that you multiply and divide fractions. Values that make the denominator of an expression zero are excluded values.
