Domain of rational function with radical in the numerator

The video tutorial explains how to handle radicals and denominators in mathematical expressions. It covers setting up inequalities, using inverse operations, and the importance of flipping signs when multiplying or dividing by negative numbers. The tutorial also demonstrates factoring techniques and the application of the zero product property. Finally, it discusses graphing the results and defining the domain, highlighting the need to exclude certain undefined values.

Describe the domain of the function discussed in the text.

What are the undefined values in the context of the domain?
