यदि \(f:A\to B\) और \(g:A\to B\) दोनों फलन हैं तथा हर \(x\in A\) के लिए (f(x)=g(x)), तो सही निष्कर्ष क्या है?
If \(f:A\to B\) and \(g:A\to B\) are functions and (f(x)=g(x)) for every \(x\in A\), what is the correct conclusion?
Explanation opens after your attempt
A. (f=g)
Concept
Two functions are equal when their domain, codomain, and values at every element are the same. The given condition gives (f=g).
Why this answer is correct
The correct answer is A. (f=g). Two functions are equal when their domain, codomain, and values at every element are the same. The given condition gives (f=g).
Exam Tip
दो फलन समान होते हैं जब उनका प्रांत, सहप्रांत और हर अवयव पर मान समान हो। यहां दी गई शर्त (f=g) देती है।
