Holes vs asymptotes which one is it?

The video tutorial explains how to identify the domain of a function, focusing on discontinuities. It covers types of discontinuities, such as removable and non-removable, and how to determine if they are holes or vertical asymptotes. The tutorial also discusses simplifying functions to identify these discontinuities.

Describe the process of simplifying a function to identify holes.

What happens to the graph of a function at a vertical asymptote?
