यदि \(f:{1,2,3,4}\to{1,2,3,4}\) और (f(x)=5-x) है, तो (f) का परिसर क्या है?
If \(f:{1,2,3,4}\to{1,2,3,4}\) and (f(x)=5-x), what is the range of (f)?
Explanation opens after your attempt
A. ({1,2,3,4})
Concept
For (x=1,2,3,4), the images are (4,3,2,1). Therefore the range is ({1,2,3,4}).
Why this answer is correct
The correct answer is A. ({1,2,3,4}). For (x=1,2,3,4), the images are (4,3,2,1). Therefore the range is ({1,2,3,4}).
Exam Tip
(x=1,2,3,4) पर छवियां (4,3,2,1) मिलती हैं। इसलिए परिसर ({1,2,3,4}) है।
