👉 In mathematics, a subdichotomy is a set of two or more points in a set such that each point on the boundary has an equal influence on the value of the function. This property allows for the creation of a new function by subtracting one of the original functions from another. For example, let's consider the function f(x) = x^2 - 4x + 3, with points A(1,0), B(1,-3), C(-1,
