Domain of a radical function by flippling the sign

The video tutorial explains how to identify the domain of a function involving square roots, emphasizing that the domain is restricted to positive values. It covers solving inequalities using inverse operations and highlights the importance of flipping the inequality sign when multiplying or dividing by a negative number. The tutorial also demonstrates how to express the domain using interval notation and graph inequalities to better understand the solution.

What is the significance of the radicand being greater than or equal to zero?

Explain how to find the values of X that satisfy the inequality presented.
