Find the domain of a rational function in factored form

The video tutorial covers rational functions, focusing on determining the implied domain by setting the denominator equal to zero. It explains the difference between solving rational and radical equations, emphasizing the zero product property to identify values not in the domain. The tutorial also demonstrates how to represent domain exclusions on a number line and concludes with a brief mention of more complex problems.

What is the process for determining the implied domain of a rational function?

Explain the difference between solving for the radical and solving for the denominator in terms of domain.

What values are not included in the domain when X equals 1 or -1?

How would you represent the domain on a number line based on the values found?

Describe the union of intervals that represent the domain identified in the text.
