Steps to determining the domain of a radical function

The video tutorial covers the concept of radicals, focusing on the square root. It explains that the radicand must be greater than or equal to zero, as square roots of negative numbers are not defined in real numbers. The tutorial guides students through setting up and solving inequalities to determine the domain of functions involving radicals. It concludes with a discussion on graphing the solution and finding the domain, ensuring students understand the process.
