What is a vertical asymptote

The video tutorial explains vertical asymptotes, focusing on their properties and representation on graphs. It describes how functions behave as they approach these asymptotes, either heading towards positive or negative infinity. The tutorial also covers the concept of asymptotic behavior, emphasizing that functions approach but do not cross asymptotes. Examples are provided to illustrate these concepts.

How can you represent a vertical asymptote on a graph?

Describe a scenario where a function might cross its vertical asymptote.
