यदि \(R=\{(1,2),(2,4),(3,6)\}\) है, तो (R) को set-builder रूप में कैसे लिखा जा सकता है?
If \(R=\{(1,2),(2,4),(3,6)\}\), how can (R) be written in set-builder form?
Explanation opens after your attempt
B. \(R=\{(x,y):y=2x\}\)
Concept
In every pair, the second component is (2) times the first. Therefore, the rule is (y=2x).
Why this answer is correct
The correct answer is B. \(R=\{(x,y):y=2x\}\). In every pair, the second component is (2) times the first. Therefore, the rule is (y=2x).
Exam Tip
हर pair में दूसरा घटक पहले का (2) गुना है। इसलिए नियम (y=2x) है।
