यदि \(A=\{2,3,5\}\) और \(B=\{4,6,10\}\) है तो नियम (f(x)=2x) से बना संबंध कौन सा है?
If \(A=\{2,3,5\}\) and \(B=\{4,6,10\}\), which relation is formed by the rule (f(x)=2x)?
Explanation opens after your attempt
A. \(f=\{(2,4),(3,6),(5,10)\}\)
Concept
For each \(x\in A\), taking (2x) gives the correct pairs. Check every input separately while applying a rule.
Why this answer is correct
The correct answer is A. \(f=\{(2,4),(3,6),(5,10)\}\). For each \(x\in A\), taking (2x) gives the correct pairs. Check every input separately while applying a rule.
Exam Tip
हर \(x\in A\) के लिए (2x) लेने पर सही युग्म मिलते हैं। नियम लागू करते समय प्रत्येक इनपुट अलग से जांचें।
