To do this, you can use the following commands:

When you are graphing discontinuous functions, often times, it can be useful to generate a vertical or horizontal asymptote. Remove // Quiet (* remove all variables *) Here are two options: either exclude discontinuities (which is a default option) or connect them There are three different functions that have been generated inĪ single graph. Using Mathematica, it is easy to plot a piecewise discontinuous function.Īn example of a Piecewise function is given below. Such function are not 'differentiable everywhere' because the limit techniques which underlie derivative methodology do not work on hard corners. Discontinuous functions are to be distinguished from 'smooth' functions, the former exhibiting a hard corner at a particular point. For example, if the denominator is ( x−1), the function will have a discontinuity at x=1. If the functions' individual domains do not use the entirety of the support, plotting them reveals they are separated by empty space.Ī discontinuous function is a function that has a discontinuity at one or more values, often because of zero in the denominator. A piecewise function is a function defined by different functions for each part of the domain of the entire function (sometimes referred to as 'the support,' indicating the x axis in 2D). There are piecewise functions and functions that are discontinuous at a point.

There are two types of discontinuous functions.
