that a rational expression can be . undefined when the denominator is equal to zero. In Algebra we called this finding the zeros or finding the extraneous roots. In Intermediate Algebra we extend this to relate to functions and their domains. The domain of a rational expression only includes the numbers for which it is a valid function.

The domain of a rational expression is the set of all numbers which can be plugged into the rational expression. To find the domain of a rational expression, find all values of the variable that cause the denominator to be zero, and exclude them from the domain. A rational expression is simplified when all common factors in the numerator and denominator have been cancelled. Examples: To multiply rational expressions…

Finding the domain of a rational expression: When you dealt with rational numbers, you encountered simple fractions. These rational numbers could have any whole numbers for the numerator and any number except for zero as the denominator. When evaluating a rational expression, you will often need to evaluate the expression, and it can be useful ...

Remember that we defined the domain of a rational expression as all possible values of the independent or x variable. Any value that makes the denominator 0 is excluded from the domain. The domain of a rational equation is the intersection of the domains of each rational expression in the equation. Find the domain of each equation:
