👉 A pluperfect function, also known as a perfect function or a complete function, is a mathematical function that is defined on all of its input values and has a unique value at every point. It is often denoted by "f(x)" or "g(x) for real numbers x." The term "pluperfect" comes from the fact that it can be extended to include any number of arguments, making it an infinitely large function. For example, if we define the function f(x
