Biggest Mistake For Domain Radical Function

The video tutorial explains how to find the domain of a square root function by setting the radicand greater than or equal to zero and solving the resulting inequality. It demonstrates solving the inequality using inverse operations and verifies the domain by testing values. The tutorial concludes with a discussion on interval notation and emphasizes the importance of verifying solutions to avoid mistakes.
