यदि \(A=\{1,2,3\}\), तो (A) से (A) में identity function और constant function (c(x)=1) में मुख्य अंतर क्या है?
If \(A=\{1,2,3\}\), what is the main difference between the identity function on (A) and the constant function (c(x)=1)?
Explanation opens after your attempt
A. identity में \(x\mapsto x\), constant में हर \(x\mapsto 1\)In identity, \(x\mapsto x\); in constant, every \(x\mapsto 1\)
Concept
Identity maps each input to itself, while a constant function sends every input to the same value. Both can be valid functions.
Why this answer is correct
The correct answer is A. identity में \(x\mapsto x\), constant में हर \(x\mapsto 1\) / In identity, \(x\mapsto x\); in constant, every \(x\mapsto 1\). Identity maps each input to itself, while a constant function sends every input to the same value. Both can be valid functions.
Exam Tip
identity input को उसी पर map करती है, जबकि constant function हर input को same value पर भेजता है। दोनों valid functions हो सकते हैं।
