यदि \(R=\{(x,y):x=|y|,\ x\in{0,1,2},\ y\in{-2,-1,0,1,2}\}\) को \(X=\{0,1,2\}\) से \(Y=\{-2,-1,0,1,2\}\) में माना जाए, तो (R) क्या है?
If \(R=\{(x,y):x=|y|,\ x\in{0,1,2},\ y\in{-2,-1,0,1,2}\}\) is considered from \(X=\{0,1,2\}\) to \(Y=\{-2,-1,0,1,2\}\), what is (R)?
Explanation opens after your attempt
B. फलन नहीं है क्योंकि (1) की छवियां (-1) और (1) हैंIt is not a function because (1) has images (-1) and (1)
Concept
For (x=1), both (y=-1) and (y=1) are possible. Two (y)-values for one (x) mean the relation is not a function.
Why this answer is correct
The correct answer is B. फलन नहीं है क्योंकि (1) की छवियां (-1) और (1) हैं / It is not a function because (1) has images (-1) and (1). For (x=1), both (y=-1) and (y=1) are possible. Two (y)-values for one (x) mean the relation is not a function.
Exam Tip
(x=1) के लिए (y=-1) और (y=1) दोनों संभव हैं। एक (x) के दो (y) होने से संबंध फलन नहीं है।
