How do you Find excluded values? - Answers

To find excluded values in a mathematical expression, especially in rational functions, identify values that make the denominator zero, as these values are undefined. Set the denominator equal to zero and solve for the variable to determine these excluded values. Additionally, for other types of functions, like square roots, identify values that lead to negative results under the square root. Always remember to consider the context of the problem to ensure all excluded values are accounted for.
