A) \[\{(11,8),(13,10)\}\]
B) \[\{(8,11),(10,13)\}\]
C) \[\{(8,11),(9,12),(10,13)\}\]
D) None of these
Correct Answer: B
Solution :
[b] We have, \[R=\{(x,y):y=x-3,x=11\]or 12 or 13, \[y=8\] or 10 or \[12\}\]\[=\{(11,8),(13,10)\}\] \[\therefore {{R}^{-1}}\{(y,x):(x,y)\in R\}=\{(8,11),(10,13)\}\]You need to login to perform this action.
