यदि \(A=\emptyset\) और \(B=\emptyset\) हों तो (A) से (B) में फलनों की संख्या क्या है?
If \(A=\emptyset\) and \(B=\emptyset\), what is the number of functions from (A) to (B)?
Explanation opens after your attempt
Correct Answer
B. (1)
Concept
From an empty domain to an empty codomain, there is one empty function. Remember this as the function-context meaning of \(0^0=1\).
Why this answer is correct
The correct answer is B. (1). From an empty domain to an empty codomain, there is one empty function. Remember this as the function-context meaning of \(0^0=1\).
Exam Tip
रिक्त प्रांत से रिक्त सहप्रांत में भी एक खाली फलन होता है। इसे सूत्र \(0^0=1\) की फलन-संदर्भ व्याख्या से याद रखें।
