यदि \(R=\{(1,3),(2,4),(3,5)\}\) है, तो (R) का परिभाषा क्षेत्र क्या है?
If \(R=\{(1,3),(2,4),(3,5)\}\), what is the domain of (R)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3} )
Step 1
Concept
The domain contains the first components of the ordered pairs. Hence the domain of (R) is ( {1,2,3} ).
Step 2
Why this answer is correct
The correct answer is A. ( {1,2,3} ). The domain contains the first components of the ordered pairs. Hence the domain of (R) is ( {1,2,3} ).
Step 3
Exam Tip
परिभाषा क्षेत्र में ordered pairs के पहले घटक लिए जाते हैं। इसलिए (R) का परिभाषा क्षेत्र ( {1,2,3} ) है।

यदि \(R=\{(2,5),(4,7),(6,9)\}\) है, तो (R) का परिसर क्या है?
If \(R=\{(2,5),(4,7),(6,9)\}\), what is the range of (R)?
Explanation opens after your attempt
Correct Answer
B. ( {5,7,9} )
Step 1
Concept
The range contains the second components of the ordered pairs. Hence the range of (R) is ( {5,7,9} ).
Step 2
Why this answer is correct
The correct answer is B. ( {5,7,9} ). The range contains the second components of the ordered pairs. Hence the range of (R) is ( {5,7,9} ).
Step 3
Exam Tip
परिसर में ordered pairs के दूसरे घटक लिए जाते हैं। इसलिए (R) का परिसर ( {5,7,9} ) है।
