What Exactly Are Relation and Function In Simple Terms?

Chapter 1 of Class 12 Maths involves Relation and Function. This chapter is of utmost importance and should not be skipped without fully understanding each and every aspect of it. Why? - Because it forms the fundamentals of Mathematics in a significant way. Without properly understanding Relation and Function, you cannot have a grasp on chapters like differential calculus, integration, Analytic Geometry, etc.

In short- 

Function - if an input value triggers a specific output value each time.

Relation-If an input value triggers different output values .

Example 1 - 

X - 3 5 8 9 3 2 8

Y - 8 1 7 4 5 12 1

In this set, the output values of 3 and 8 input values are different in two places. This is an example where the set of values represent Relation.

Example 2 - 

X - 3 5 8 9 3 2 8

Y - 8 1 7 4 8 12 7
