What students always forget when writing the domain

The video tutorial explains how to find the domain of functions with both radicals and rational expressions. It highlights common student mistakes, such as focusing only on radicals and forgetting rational function restrictions. The instructor provides tips for solving domain problems, including setting radicals greater than or equal to zero and denominators equal to zero. The tutorial emphasizes the importance of finding the intersection of domains and uses graphical methods to illustrate this concept. The video aims to enhance understanding of domain restrictions, especially when dealing with multiple functions.

What is the difference between the restrictions found from the radical function and the rational function?

Describe the process of finding the intersection of two domains.

How can graphing the domains separately help in finding the overall domain?
