Determine the domain of a rational function
WebJul 13, 2024 · Find the Domain of a Rational Function. Division by zero is undefined. Having a zero as the denominator is equivalent to division by zero thus is also undefined. The rational function is undefined for any value of the variable that gives a zero denominator. Find these values by creating an equation to solve.
