👉 In mathematics, a discontinuous function is a function that has jumps or breaks at its values. In other words, it can have many local extrema (or inflection points) and no global extremum (the maximum or minimum point). This means that every value of the function has one or more "jump" points where it changes from being positive to negative or vice versa. For example, consider the function f(x) = x^2 - 4x + 3. At x
