यदि \(A=\emptyset\) और \(B=\emptyset\) हों, तो (A) से (B) में फलनों की संख्या और उस फलन के ग्राफ में ordered pairs की संख्या क्रमशः क्या है?
If \(A=\emptyset\) and \(B=\emptyset\), what are respectively the number of functions from (A) to (B) and the number of ordered pairs in the graph of that function?
Explanation opens after your attempt
Correct Answer
A. (1) और (0)(1) and (0)
Concept
There is one empty function from the empty domain, but its graph has no ordered pair. Keep the count and graph size separate.
Why this answer is correct
The correct answer is A. (1) और (0) / (1) and (0). There is one empty function from the empty domain, but its graph has no ordered pair. Keep the count and graph size separate.
Exam Tip
रिक्त प्रांत से एक खाली फलन होता है, लेकिन उसके ग्राफ में कोई ordered pair नहीं होता। संख्या और ग्राफ-आकार को अलग रखें।
