Discontinuities may be classified as removable, jump, or infinite. A function is continuous over an open interval if it is continuous at every point in the interval. It is continuous over a closed interval if it is continuous at every point in its interior and is continuous at its endpoints.

It discusses the types of discontinuities (removable, jump, and infinite) and provides examples to illustrate these concepts. The section also covers the Intermediate Value Theorem, which relies on continuity to guarantee the existence of certain values within an interval.

This function is an example. A function that has any hole or break in its graph is known as a discontinuous function. A stepwise function, such as parking-garage charges as a function of hours parked, is an example of a discontinuous function. We can check three different conditions to decide if a function is continuous at a particular number.
