A function is a special type of relation where every input has a unique output. Definition: A function is a correspondence between two sets (called the domain and the range) such that to each element of the domain, there is assigned exactly one element of the range.

A function is a relation in which each input has only output.In the relation,Y is a function of X,because for each input X(1,2,3 or 0),there is only one output Y.X is not a function of Y, because the input Y=3 has multiple outputs:X=1 and X=2
