यदि \(A=\{0,1,2\}\) और \(B=\{1,2,3,4\}\) हों, तथा (f(x)=x+2) हो, तो कौन-सा क्रमित युग्म (f) में नहीं होगा?
If \(A=\{0,1,2\}\) and \(B=\{1,2,3,4\}\), and (f(x)=x+2), which ordered pair will not be in (f)?
Explanation opens after your attempt
D. ((2,3))
Concept
(f(2)=2+2=4), so ((2,3)) will not be in this function. In exams, match each pair with the rule.
Why this answer is correct
The correct answer is D. ((2,3)). (f(2)=2+2=4), so ((2,3)) will not be in this function. In exams, match each pair with the rule.
Exam Tip
(f(2)=2+2=4), इसलिए ((2,3)) इस फलन में नहीं होगा। परीक्षा में हर युग्म को नियम से मिलाएं।
