यदि \(f:{1,2,3,4,5}\to{1,2,3,4,5}\) को (f(x)=x) जब (x) अभाज्य हो और (f(x)=6-x) अन्यथा दिया गया है, तो परिसर क्या है?
If \(f:{1,2,3,4,5}\to{1,2,3,4,5}\) is given by (f(x)=x) when (x) is prime and (f(x)=6-x) otherwise, what is the range?
Explanation opens after your attempt
A. ({1,2,3,5})
Concept
The values are (f(1)=5), (f(2)=2), (f(3)=3), (f(4)=2), and (f(5)=5). Therefore the range is ({2,3,5}).
Why this answer is correct
The correct answer is A. ({1,2,3,5}). The values are (f(1)=5), (f(2)=2), (f(3)=3), (f(4)=2), and (f(5)=5). Therefore the range is ({2,3,5}).
Exam Tip
मान (f(1)=5), (f(2)=2), (f(3)=3), (f(4)=2), (f(5)=5) हैं। इसलिए परिसर ({2,3,5}) नहीं बल्कि ({2,3,5}) है।
