👉 In mathematics, a discontinuous function is a function that has one or more values at points where it fails to be continuous. This means that the function may have jumps or infinite values at those points. For example, consider the function f(x) = x^2 - 1 for all real numbers x. At points where x=0, the value of f(x) is undefined (since there are no values in the domain of f), and the function fails to be continuous at these points
