कौन-सा संबंध \(A=\{1,2,3\}\) से \(B=\{p,q,r\}\) में फलन नहीं है?
Which relation from \(A=\{1,2,3\}\) to \(B=\{p,q,r\}\) is not a function?
Explanation opens after your attempt
Correct Answer
C. \(R=\{(1,p),(2,q),(2,r),(3,p)\}\)
Concept
Here \(2\in A\) has two images (q) and (r). In a function, one input cannot have two different outputs.
Why this answer is correct
The correct answer is C. \(R=\{(1,p),(2,q),(2,r),(3,p)\}\). Here \(2\in A\) has two images (q) and (r). In a function, one input cannot have two different outputs.
Exam Tip
यहां \(2\in A\) की दो images (q) और (r) हैं। फलन में एक input की दो अलग outputs नहीं हो सकतीं।
