👉 In mathematics, a non-derisive function is a function that is not continuous at any point. It means that if you take two different points in its domain and evaluate it at those points, the result will be different for both points.
For example:
Let f(x) = x^2 - 3x + 2.
We can see that f(1) = 1^2 - 3
1 + 2 = 1 - 3 + 2 =
