Continuous functions are of utmost importance in mathematics, functions and applications. However, not all functions are continuous. If a function is not continuous at a limit point (also …

What are the types of discontinuities? Explained with examples, pictures and several practice problems

Discontinuities are typically categorized as removable or non-removable (jump/infinite). A removable discontinuity is a discontinuity that results when the limit of a function exists but is …

In plain English, what that means is that the function passes through every point, and each point is close to the next: there are no drastic jumps (unlike jump discontinuities). When you’re …

- [Instructor] What we're going to do in this video is talk about the various types of discontinuities that you've probably seen when you took algebra, or precalculus, but then relate it to our …

x!a does not exist. Note: The discontinuity is called essential because there is no way to eliminate it by redefining the value of f(x) at x = a. There are three basic types of essential discontinuities:

Jun 6, 2025 · What Is a Discontinuity? A function is continuous at a point if its graph has no gaps there. Informally, a continuous curve can be drawn without lifting the pencil. A discontinuity is …

Essential discontinuities of all types are often referred to as \singularities": they’re points at which the function is genuinely very badly-behaved.

Discontinuities tell us where a function changes behavior. They are important in real-world modeling: for example, jumps in pricing, holes in data, or boundaries in physics.

Yes, a function can have multiple discontinuities of any type. For example, a piecewise function might have a jump discontinuity at one point and a removable discontinuity at another.
