A) \[\{(8,\,11),\,(10,13)\}\]
B) \[\{(11,\,8),\,(13,10)\}\]
C) \[\{(10,\,13),\,(8,11),\,(12,\,10)\}\]
D) None of the above
Correct Answer: A
Solution :
Given, \[y=(x-3)\] When, \[x=11,\] \[y=11-3=8\] When \[x=12,\,\,\,\,\,y=12-3=9\] When \[x=13,\,\,\,y=13-3=10\] \[\therefore \] \[R=\{(11,8),\,\,(13,\,10)\}\] \[\Rightarrow \] \[{{R}^{-1}}=\{(8,\,11),\,\,(10,13)\}\]You need to login to perform this action.
