Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in maths is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in maths. These functions are usually denoted by letters such as f, g, and h. A function relates each element of a set with exactly one element of another set (possibly the same set).
