Question: What is the Relation?
Answer:
Let us consider two sets A and B. Then a relation R from Set A into Set B is defined as the subset of A × B. The relation can be classified into three different types, such as:
Reflexive Relation
Symmetric Relation
Transitive Relation
What is a Function?
Answer:
A function is defined as the relation between two sets, in which every element in the set 1 associate to the elements in set 2. In other words, if “f” is a function from A to B, then every element in the set B is the image of an element in set A. The different types of functions are:
One to One function
One to Many functions
Onto function
One to one Correspondence
