Define a relation

Answer :

Given,


R = {(x, y): y = x + 5, x is a natural less than 4, x, y N}


Natural numbers less than 4 are 1, 2 and 3.


On putting x= 1, y = 1 + 5 = 6


On putting x= 2, y = 2 + 5 = 7


On putting x= 3, y = 3 + 5 = 8


i. R = {(1, 6), (2, 7), (3, 8)}



So,


Domain of relation R= {1, 2, 3}


Range of relation R= {6, 7, 8}
