\(f:{1,2,3}\to{2,3,4}\), (f(x)=x+1) और \(g:{1,2,3}\to{2,3,4,5}\), (g(x)=x+1) हैं। क्या (f) और (g) समान फलन हैं?
Let \(f:{1,2,3}\to{2,3,4}\), (f(x)=x+1), and \(g:{1,2,3}\to{2,3,4,5}\), (g(x)=x+1). Are (f) and (g) equal functions?
Explanation opens after your attempt
B. नहीं, क्योंकि सहप्रांत अलग हैंNo, because the codomains are different
Concept
Equality of functions also requires the codomain to be the same. The same formula alone is not sufficient.
Why this answer is correct
The correct answer is B. नहीं, क्योंकि सहप्रांत अलग हैं / No, because the codomains are different. Equality of functions also requires the codomain to be the same. The same formula alone is not sufficient.
Exam Tip
फलन की समानता में सहप्रांत भी समान होना चाहिए। केवल समान सूत्र पर्याप्त नहीं है।
