Question

Let R is relation from (11, 12, 13) to {8,10,12)
defined by y = x -3. Then,R' is​

Answer 1

ATQ

relation is defined from (11,12,13) to (8,10,12) by y=x-3

putting all possible values of x in equation y=x-3

if x=11

y = 11-3 = 8

if x= 12

y= 12-3 =9 (but 9 doesnt exist in y set)

if x= 13

y = 13-3=10

Required relation R = { (11,8),(13,10) }

R' = { (8,11),(10,13) }
