Removable discontinuities from a graph

The video tutorial explains how to determine if a function is continuous by using the pencil test on a graph. It introduces the concept of discontinuities, distinguishing between removable and non-removable types. Removable discontinuities are identified by holes in the graph, while non-removable ones include jump discontinuities and vertical asymptotes. The tutorial emphasizes using X values to locate discontinuities within the domain.

What are the characteristics of a jump discontinuity?

Where do you typically find vertical asymptotes in relation to discontinuities?
