यदि \(f:{1,2,3,4}\to{1,2,3,4}\) को (f(x)=x) जब (x) सम हो और (f(x)=5-x) जब (x) विषम 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 even and (f(x)=5-x) when (x) is odd, what is the range?
Explanation opens after your attempt
B. ({2,4})
Concept
Here (f(1)=4), (f(2)=2), (f(3)=2), and (f(4)=4), so the range is ({2,4}). For a piecewise rule list every input value.
Why this answer is correct
The correct answer is B. ({2,4}). Here (f(1)=4), (f(2)=2), (f(3)=2), and (f(4)=4), so the range is ({2,4}). For a piecewise rule list every input value.
Exam Tip
(f(1)=4), (f(2)=2), (f(3)=2), (f(4)=4), इसलिए परिसर ({2,4}) है। खंडित नियम में हर इनपुट का मान लिखें।
