A function is a relation between two sets defined in such a way that for each element in the first set, the value that corresponds to it in the second set is unique. Let f be a function defined from the set A into set B. Then for each x Ïµ A, the symbol f (x) denotes the unique value in the set B that corresponds to x. It is called the image of x under f. Therefore, a relation f from A into B is a function, if and only if for, each xÏµ A and y Ïµ A; if x = y then f (x) = f (y). The set A is called the domain of the function f, and it is the set in which the function is defined. For example, consider the relation f from R into R defined by f (x) = x + 2 for each xÏµ A. This is a function whose domain is R, as for each real number x and y, x = y implies f (x) = x + 2 = y + 2 = f (y).
