Function is well defined

WebSo, using the definition, to demonstrate that a function is well defined you must find its domain set, its target set (unless they are given to you already), and make sure that the … WebThe term used to describe this behavior is to say that f is not well-defined. Suppose you have some procedure f that takes as input an element of a set X, and returns as output an element of a set Y. Then you may only call f a function if you can prove that x = y implies f(x) = f(y). This might seem obvious at first, but it is often non-trivial.
