Desmos is a free online graphing calculator that can be used to plot functions, analyze data, and perform a variety of mathematical operations. One of the features of Desmos is the ability to view discontinuities in functions. A discontinuity is a point where the function is not defined or where the function has a sudden change in value.
There are two main types of discontinuities: removable discontinuities and non-removable discontinuities. Removable discontinuities occur when the function is not defined at a point, but the limit of the function as the input approaches the point exists. Non-removable discontinuities occur when the limit of the function as the input approaches the point does not exist.
