Find the values that the equation are not defined for

The video tutorial explains when values in mathematical expressions are undefined, focusing on rational expressions with denominators and radical expressions. It highlights two main constraints: denominators cannot be zero, and radicands must be non-negative. The teacher provides an example problem to illustrate these concepts and demonstrates how to solve for X by setting the denominator to zero and the radicand to be greater than or equal to zero.

What values of X are considered undefined for the function discussed in the example?

How can you express the condition for a radical to be defined?
