किस विकल्प में संबंध (R) \(A=\{0,1,2\}\) से \(B=\{0,1,2\}\) में फलन है लेकिन \(R^{-1}\) फलन नहीं है?
In which option is relation (R) a function from \(A=\{0,1,2\}\) to \(B=\{0,1,2\}\), but \(R^{-1}\) is not a function?
Explanation opens after your attempt
Correct Answer
B. ({(0,1),(1,1),(2,2)})
Concept
Option (B) is a function, but in the inverse relation (1) has images (0) and (1). Hence \(R^{-1}\) is not a function.
Why this answer is correct
The correct answer is B. ({(0,1),(1,1),(2,2)}). Option (B) is a function, but in the inverse relation (1) has images (0) and (1). Hence \(R^{-1}\) is not a function.
Exam Tip
विकल्प (B) फलन है, पर उल्टे संबंध में (1) की छवियां (0) और (1) होंगी। इसलिए \(R^{-1}\) फलन नहीं है।
