यदि \(f:{2,3,4}\to{0,1,2}\) को (f(x)=x-2) से परिभाषित किया जाए, तो (f) का परिसर क्या है?
If \(f:{2,3,4}\to{0,1,2}\) is defined by (f(x)=x-2), what is the range of (f)?
Explanation opens after your attempt
A. ({0,1,2})
Concept
(f(2)=0), (f(3)=1), and (f(4)=2), so the range is ({0,1,2}). In exams, changing the domain changes the range too.
Why this answer is correct
The correct answer is A. ({0,1,2}). (f(2)=0), (f(3)=1), and (f(4)=2), so the range is ({0,1,2}). In exams, changing the domain changes the range too.
Exam Tip
(f(2)=0), (f(3)=1) और (f(4)=2), इसलिए परिसर ({0,1,2}) है। परीक्षा में डोमेन बदलने से परिसर भी बदलता है।
