Domain of a radical with negative under the radical

The video tutorial explains how to determine the domain of a function involving a radical expression. It begins by discussing the necessity for the expression under the radical to be non-negative. The tutorial then demonstrates solving inequalities to find the domain, emphasizing the importance of flipping the inequality sign when multiplying or dividing by a negative number. Finally, it covers converting inequalities into interval notation, providing tips for those who may find the process challenging.
