Function and its Values with UMS

A function f with domain X and codomain Y is commonly denoted by f: XY, the elements of X are called arguments of f. For each argument x, the corresponding unique y in the codomain is called the function value at x or the image of x, under f . It is written as f(x). One says that f associates y with x or maps x to y. This is abbreviated by y=f(x).
