How to write the domain of a rational function with a radical

The video tutorial explains how to determine where a function is not defined by identifying restrictions such as when the denominator is zero or when the radicand is negative for even roots. It also covers how to find the domain of a function by identifying the values where the function is defined.

What are the two restrictions that make a function not defined?

Explain how to determine the values that make the denominator equal to zero.

What happens to the function when X equals 3?

Describe the process to find the values where the radicand is negative.

What is the defined range of the function based on the inequalities discussed?

Identify the values where the function is not defined.

How do you express the domain of the function based on the discussion?
