Find the Domain of a Rational Function | Compilation

The video tutorial explains how to find the domain of rational functions by working through five examples. It covers restrictions due to denominators, the use of interval notation, the zero product property, handling multiple restrictions, and factoring to identify domain constraints. The tutorial emphasizes understanding the concept of domain in rational functions and provides practical examples to illustrate these concepts.

What are the implications of having a variable in the denominator of a rational function?

How do you write the domain in interval notation when there are excluded values?

Why is it important to check for restrictions in both the numerator and denominator?

What is the role of the numerator in determining the domain of a rational function?
