संबंध \(R=\{(x,y):|x-y|=1,\ x\in{1,2,3},\ y\in{1,2,3,4}\}\) को (X) से (Y) में माना गया है। यह फलन क्यों नहीं है?
The relation \(R=\{(x,y):|x-y|=1,\ x\in{1,2,3},\ y\in{1,2,3,4}\}\) is considered from (X) to (Y). Why is it not a function?

Correct Answer
B. क्योंकि (x=2) की दो छवियां हैंBecause (x=2) has two images
Concept
At (x=2), both (y=1) and (y=3) occur. A function must have only one output for each input.
Why this answer is correct
The correct answer is B. क्योंकि (x=2) की दो छवियां हैं / Because (x=2) has two images. At (x=2), both (y=1) and (y=3) occur. A function must have only one output for each input.
Exam Tip
(x=2) पर (y=1) और (y=3) दोनों मिलते हैं। फलन में हर इनपुट के लिए केवल एक आउटपुट होना चाहिए।
