TO IDENTIFY
The distinction between a relation and a function with suitable examples and to illustrate graphically
EVALUATION
RELATION
Let S and T be two non empty sets. A relation R between S and T is a subset of S × T
EXAMPLE
Let S = { 2 , 3 , 4 , 5 } and
T = { 11 , 12 , 13 , 14 }
A relation R between S and T defined as
Here 2 in S is related to two elements 12 & 14 of T , but 5 in S in not related to no element of T by the relation R
FUNCTION
Let A and B are two non empty sets. If f is a relation between A and B with the property that every element x of A is related exactly one element y of B is said to be a Function from A to B
EXAMPLE
Let S = { 2 , 3 , 4 , 5 } and
T = { 11 , 12 , 13 , 14 }
Then every element x of A is related exactly one element y of B
Hence f is a function
