To the right of, the graph goes to, and to the left it goes to. For example, (from our "removable discontinuity" example) has an infinite discontinuity at.
A real-valued univariate function is said to have an infinite discontinuity at a point in its domain provided that either (or both) of the lower or upper limits of goes to positive or negative infinity as tends to. Ī third type is an infinite discontinuity. A real-valued univariate function has a jump discontinuity at a point in its domain provided that and both exist, are finite and that. For example, the floor function has jump discontinuities at the integers at, it jumps from (the limit approaching from the left) to (the limit approaching from the right). Informally, the function approaches different limits from either side of the discontinuity. Put formally, a real-valued univariate function is said to have a removable discontinuity at a point in its domain provided that both and exist.Īnother type of discontinuity is referred to as a jump discontinuity. Informally, the graph has a "hole" that can be "plugged." For example, has a discontinuity at (where the denominator vanishes), but a look at the plot shows that it can be filled with a value of.
The simplest type is called a removable discontinuity. Given a one-variable, real-valued function, there are many discontinuities that can occur. What are discontinuities? A discontinuity is a point at which a mathematical function is not continuous.

Here are some examples illustrating how to ask for discontinuities. To avoid ambiguous queries, make sure to use parentheses where necessary. It also shows the step-by-step solution, plots of the function and the domain and range.Įnter your queries using plain English. Wolfram|Alpha is a great tool for finding discontinuities of a function.
