यदि \(A=\{1,2,3\}\), \(B=\{2,4,6\}\) और \(f=\{(1,2),(2,4),(3,6)\}\), तो domain क्या है?
If \(A=\{1,2,3\}\), \(B=\{2,4,6\}\), and \(f=\{(1,2),(2,4),(3,6)\}\), what is the domain?
Explanation opens after your attempt
A. \({1,2,3})
Concept
The domain is the set of first coordinates, and here \(A=\{1,2,3\}\). Distinguish ordered pairs from the domain.
Why this answer is correct
The correct answer is A. \({1,2,3}). The domain is the set of first coordinates, and here \(A=\{1,2,3\}\). Distinguish ordered pairs from the domain.
Exam Tip
domain first coordinates का set है और यहां \(A=\{1,2,3\}\) है। ordered pairs और domain को अलग-अलग पहचानें।
