Functions and relations are found everywhere in maths. We can define as relation as a set of ordered pair connected together in a well defined manner. On the other hand, a function is a relation which has only one output value of each permitted or allowed input value. There are several different kinds of functions. Polynomial function is one of the important ones. As the name polynomial itself indicates, poly stands for many and nomial suggests terms. Thus, the function which contains many terms is called as a polynomial.
