यदि \(A=\{2,3,4\}\), \(B=\{4,9,16,25\}\) और (f(x)=x-2) हो, तो सहप्रांत का कौन-सा तत्व परिसर में नहीं आएगा?
If \(A=\{2,3,4\}\), \(B=\{4,9,16,25\}\), and (f(x)=x-2), which element of the codomain will not be in the range?
Explanation opens after your attempt
D. (25)
Concept
The range is ({4,9,16}), so (25) is not obtained. In exams, every codomain element need not be in the range.
Why this answer is correct
The correct answer is D. (25). The range is ({4,9,16}), so (25) is not obtained. In exams, every codomain element need not be in the range.
Exam Tip
परिसर ({4,9,16}) है, इसलिए (25) प्राप्त नहीं होता। परीक्षा में सहप्रांत का हर तत्व जरूरी नहीं कि परिसर हो।
