The concept of function is central to mathematics. A function is a rule assigning values to certain objects. If a function is called f, the value it assigns to x is denoted by f (x). A well-defined function f assigns to each such x a single value f (x). However, several objects x1, x2,. . . , x n may get the same value f (x1) = f (x2) = . . . =f(x n ). Here are some examples.
