Let \(A=\{0,1,2\}\) and \(B=\{1,2,3,4\}\). Which statement is correct for \(R=\{(0,1),(1,2),(2,3),(2,4)\}\)?
Explanation opens after your attempt
B. यह फलन नहीं है क्योंकि (2) की दो छवियां हैंIt is not a function because (2) has two images
Concept
The element (2) is linked to both (3) and (4), so the single-image condition fails. Having all first elements is not enough.
Why this answer is correct
The correct answer is B. यह फलन नहीं है क्योंकि (2) की दो छवियां हैं / It is not a function because (2) has two images. The element (2) is linked to both (3) and (4), so the single-image condition fails. Having all first elements is not enough.
Exam Tip
(2) से (3) और (4) दोनों जुड़े हैं, इसलिए एकल छवि की शर्त टूटती है। केवल सभी प्रथम अवयव आना पर्याप्त नहीं है।
