यदि \(f:{1,2,3}\to{0,1}\) को (f(x)=0) सभी \(x\in{1,2,3}\) के लिए परिभाषित किया गया है, तो (f) का परिसर क्या है?
If \(f:{1,2,3}\to{0,1}\) is defined by (f(x)=0) for all \(x\in{1,2,3}\), what is the range of (f)?

Correct Answer
A. ({0})
Concept
All elements have image (0), so the range is ({0}). In exams, do not include an unattained codomain element in the range.
Why this answer is correct
The correct answer is A. ({0}). All elements have image (0), so the range is ({0}). In exams, do not include an unattained codomain element in the range.
Exam Tip
सभी तत्वों की छवि (0) है इसलिए परिसर ({0}) है। परीक्षा में सहप्रांत में मौजूद पर अप्राप्त तत्व को परिसर में न लिखें।
