Finding the domain when the radical is in numerator, denominator and both

The video tutorial explains how to determine the domain of functions involving rational and radical expressions. It covers the importance of identifying restrictions in both the numerator and denominator, especially when radicals are involved. The instructor demonstrates solving for domain restrictions using inverse operations and emphasizes the need to consider the intersection of restrictions. The tutorial also discusses the implications of having radicals in the denominator and how to graphically represent these restrictions on a number line.

What happens to the restrictions when the radical is moved to the denominator?

Describe the steps to take when a radical is present in the denominator of a rational function.

In the context of rational functions, why is it important to ensure that the radical does not equal zero?
