यदि \(R=\{(1,a),(2,b),(2,c),(3,a)\}\) है, तो इसे फलन बनाने के लिए कौन-सा युग्म हटाना पर्याप्त होगा?
If \(R=\{(1,a),(2,b),(2,c),(3,a)\}\), which pair is sufficient to remove to make it a function?
Explanation opens after your attempt
Correct Answer
A. ((2,c))
Concept
(2) has two images and after removing ((2,c)) every first component has exactly one image. In exams, remove one pair from the repeated first component.
Why this answer is correct
The correct answer is A. ((2,c)). (2) has two images and after removing ((2,c)) every first component has exactly one image. In exams, remove one pair from the repeated first component.
Exam Tip
(2) की दो छवियां हैं और ((2,c)) हटाने पर हर पहले घटक की ठीक एक छवि रह जाएगी। परीक्षा में दोहराए पहले घटक से एक युग्म हटाएं।
