Definition: In mathematics, a polyonomous is a set of functions that are defined in terms of each other. These functions can be considered as a group or a system of equations. For example, if we have two sets S1 and S2, then they are called polyonomous if there exists a function f: S1 → S2 such that for every x ∈ S1, f(x) ∈ S2. For instance, consider the function f(x) = x^3 - 4x
