What happens to the domain with a radical in the denominator

The video tutorial covers rational expressions, focusing on the importance of the denominator not being zero. It explains how to solve inequalities involving radicals, emphasizing the need to adjust the inequality when the radical is in the denominator. The tutorial concludes with graphing the solution set of the inequalities, ensuring students understand the exclusion of certain values.

Why is it important to change the inequality to greater than instead of greater than or equal to?

What is the significance of excluding certain values when graphing the function?
