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
Correct Answer

A. ({1,2,3,4})

Step 1

Concept

For (x=1,2,3,4), the images are (4,3,2,1). Therefore the range is ({1,2,3,4}).

Step 2

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}).

Step 3

Exam Tip

(x=1,2,3,4) पर छवियां (4,3,2,1) मिलती हैं। इसलिए परिसर ({1,2,3,4}) है।
