यदि \(A=\emptyset\) और \(B=\{5,6\}\) हों, तो (A) से (B) में फलन के ग्राफ में ordered pairs की संख्या कितनी होगी?
If \(A=\emptyset\) and \(B=\{5,6\}\), how many ordered pairs are in the graph of the function from (A) to (B)?
Explanation opens after your attempt
Correct Answer
A. (0)
Concept
There is one empty function from the empty domain, and its graph has no ordered pair. The number of functions and the number of graph pairs are different facts.
Why this answer is correct
The correct answer is A. (0). There is one empty function from the empty domain, and its graph has no ordered pair. The number of functions and the number of graph pairs are different facts.
Exam Tip
रिक्त प्रांत से एक खाली फलन होता है, और उसके ग्राफ में कोई ordered pair नहीं होता। फलनों की संख्या और ग्राफ के युग्मों की संख्या अलग बातें हैं।
