यदि \(A=\{2,3,4,5\}\) पर \(R=\{(a,b):a-b=1\}\), तो (R) का परिसर क्या है?
If \(R=\{(a,b):a-b=1\}\) on \(A=\{2,3,4,5\}\), what is the range of (R)?
Explanation opens after your attempt
A. ( {2,3,4} )
Concept
The pairs are ( (3,2),(4,3),(5,4) ), so the range is ( {2,3,4} ). In exams, take second components for range.
Why this answer is correct
The correct answer is A. ( {2,3,4} ). The pairs are ( (3,2),(4,3),(5,4) ), so the range is ( {2,3,4} ). In exams, take second components for range.
Exam Tip
युग्म ( (3,2),(4,3),(5,4) ) हैं, इसलिए परिसर ( {2,3,4} ) है। परीक्षा में range के लिए दूसरे घटक लें।
