Domain of a radical function in interval notation

The video tutorial explains how to handle radicals in mathematical expressions, focusing on solving inequalities where the expression under the radical must be non-negative. It demonstrates solving these inequalities and representing solutions on a number line. The tutorial also covers the graphical interpretation of these solutions, emphasizing the importance of including or excluding endpoints in interval notation.
