WebWell-defined is a property of functions; well-formed is a property of logical propositions. A well-defined function is any function that is single-valued (see Tim Gowers's site for a good explanation) and a well-formed proposition is any proposition that makes sense syntactically.

WebJul 7, 2024 · Therefore, \(f^{-1}\) is a well-defined function. If a function \(f\) is defined by a computational rule, then the input value \(x\) and the output value \(y\) are related by the equation \(y=f(x)\). In an inverse function, the role of the input and output are switched. Therefore, we can find the inverse function \(f^{-1}\) by following these ...

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.
