To determine the values that make a rational expression undefined, one must identify the denominator of the expression and set it equal to zero, as division by zero is undefined in mathematics. By solving the equation formed, you can find the specific values of the variable that lead to an undefined expression. These values are crucial to consider, particularly in graphing functions or simplifying expressions, since they indicate restrictions on the domain of the rational function.
