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
Correct Answer

D. (25)

Step 1

Concept

The range is ({4,9,16}), so (25) is not obtained. In exams, every codomain element need not be in the range.

Step 2

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.

Step 3

Exam Tip

परिसर ({4,9,16}) है, इसलिए (25) प्राप्त नहीं होता। परीक्षा में सहप्रांत का हर तत्व जरूरी नहीं कि परिसर हो।
