R is a relation from {11, 12, 13} to {8,...

`R` is a relation from {11, 12, 13} to {8, 10, 12} defined by `y=x-3` . Then, `R^(-1)` is

A

`{(8, 11), (10, 13)}`

B

`{(11, 18), (13, 10)}`

C

`{(10, 13), (8, 11)}`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Given, `y=x-3impliesx-y=3`
`:." "R={(11,8),(13,10)}impliesR^(-1)={(8,11),(10,13)}`
