Writing the domain of a rational function with a radical in the denominator

The video tutorial explains how to handle mathematical expressions involving radicals and denominators. It introduces two main restrictions: the expression under the radical must be non-negative, and the denominator cannot be zero. The tutorial walks through solving these restrictions, using a number line to illustrate the inclusion and exclusion of values. It emphasizes the importance of understanding these restrictions to determine the domain of the expression.
