यदि \(A=\{1,2,3\}\) और \(B=\{0,1,2,3\}\), तो relation \(R=\{(x,y):y<x,\ x\in A,\ y\in B\}\) किस कारण फलन नहीं है?
If \(A=\{1,2,3\}\) and \(B=\{0,1,2,3\}\), why is the relation \(R=\{(x,y):y<x,\ x\in A,\ y\in B\}\) not a function?
Explanation opens after your attempt
A. (x=3) के लिए (y=0,1,2) possible हैंFor (x=3), (y=0,1,2) are possible
Concept
For (x=3), there are many images, so uniqueness fails. In inequality relations, count possible outputs for one input.
Why this answer is correct
The correct answer is A. (x=3) के लिए (y=0,1,2) possible हैं / For (x=3), (y=0,1,2) are possible. For (x=3), there are many images, so uniqueness fails. In inequality relations, count possible outputs for one input.
Exam Tip
(x=3) की कई images हैं, इसलिए uniqueness टूटती है। inequality वाले relations में एक input पर possible outputs गिनें।
