Domain of a function with radical in the denominator #shorts

The video tutorial explains how to handle rational functions with square roots in the denominator. It covers the implied domain restrictions for both rational and square root functions, and demonstrates how to combine these restrictions effectively. The tutorial then applies these combined restrictions to solve the problem, concluding with a representation of the domain using interval notation.

What does it mean to have an open circle on a number line when representing a domain?

Describe the interval notation for the domain of the function discussed in the text.
