👉 In mathematics, a horn function is a type of function that has a singularity at every point except for one value. This means that the function can be represented as an infinite series or sum without any real zeros. For example, consider the function f(x) = x^3 - 2x^2 + 4x - 8 in the interval [-10, 10]. The graph of this function is a bowl-shaped curve with four discontinuities at x=0
