How to write the domain in interval notation with a factored denominator

The video tutorial introduces examples without radicals and focuses on understanding restrictions in the denominator. It explains the zero product property and how to apply it to solve equations. The tutorial discusses undefined values, asymptotes, and how to represent them on a number line. Finally, it defines the domain of a function using intervals, highlighting the importance of understanding undefined values and their impact on the domain.
