How to Find Vertical Asymptotes

We describe what it means to have either infinite or negative infinity limits of f(x) approach. From the numerical, graphical and symbolic points of view, we examine this definition. Using this definition we describe what a vertical asymptote is meant to mean.

The student should understand the definition of what it means to say that a limit is infinity after learning through these materials.

When graphing, remember that vertical asymptotes stand for x-values that are not allowed. Vertical asymptotes are sacred ground. Never, on pain of death, can you cross a vertical asymptote. Don't even try
