यदि \(A=\{1,2\}\) और \(B=\{3,4,5\}\) हों, तो \(A\times B\) के किस उपसमुच्चय को (A) से (B) में फलन कहा जा सकता है?
If \(A=\{1,2\}\) and \(B=\{3,4,5\}\), which subset of \(A\times B\) can be called a function from (A) to (B)?
Explanation opens after your attempt
Correct Answer
A. ({(1,3),(2,5)})
Concept
In option (A), both (1) and (2) have exactly one image. In exams, check the whole domain before calling a subset a function.
Why this answer is correct
The correct answer is A. ({(1,3),(2,5)}). In option (A), both (1) and (2) have exactly one image. In exams, check the whole domain before calling a subset a function.
Exam Tip
विकल्प (A) में (1) और (2) दोनों की ठीक एक छवि है। परीक्षा में उपसमुच्चय को फलन कहने से पहले पूरा प्रांत जांचें।
