Domain with radical in the numerator

The video tutorial explains how to determine the domain of a function with a radical in the numerator and a polynomial in the denominator. It covers the restrictions imposed by the square root in the numerator and the need to factor the denominator to find values that make it zero. The tutorial demonstrates how to apply the zero product property and graph the domain, highlighting the importance of excluding certain values. The session concludes with a practical example to reinforce the concepts.
