Correct Answer
A. ({1,2,3,4})
Concept
The values look like (5,4,3,2,1,1), but (5) is not in the codomain, so it is not a valid function. The correct check must first test codomain membership.
Why this answer is correct
The correct answer is A. ({1,2,3,4}). The values look like (5,4,3,2,1,1), but (5) is not in the codomain, so it is not a valid function. The correct check must first test codomain membership.
Exam Tip
मान (5,4,3,2,1,1) दिखते हैं लेकिन (5) सहप्रांत में नहीं है, इसलिए यह वैध फलन नहीं है। सही जांच में पहले सहप्रांत की सदस्यता देखनी चाहिए।
