यदि \(f:{1,2,3,4}\to{1,2,3,4}\) को (f(x)=x) जब (x) विषम हो और (f(x)=5-x) जब (x) सम हो, तो परिसर क्या है?
If \(f:{1,2,3,4}\to{1,2,3,4}\) is given by (f(x)=x) when (x) is odd and (f(x)=5-x) when (x) is even, what is the range?
Explanation opens after your attempt
Correct Answer
A. ({1,3})
Concept
The values are (f(1)=1), (f(2)=3), (f(3)=3), and (f(4)=1). Hence the range is ({1,3}).
Why this answer is correct
The correct answer is A. ({1,3}). The values are (f(1)=1), (f(2)=3), (f(3)=3), and (f(4)=1). Hence the range is ({1,3}).
Exam Tip
मान (f(1)=1), (f(2)=3), (f(3)=3), (f(4)=1) हैं। अतः परिसर ({1,3}) है।
