यदि \(A=\{-1,0,1,2\}\) और \(B=\{0,1,4\}\) हों, तथा (f(x)=x-2) हो, तो (f) का परिसर क्या है?
If \(A=\{-1,0,1,2\}\) and \(B=\{0,1,4\}\), and (f(x)=x-2), what is the range of (f)?
Explanation opens after your attempt
Correct Answer
A. ({0,1,4})
Concept
(f(-1)=1), (f(0)=0), (f(1)=1), and (f(2)=4), so the range is ({0,1,4}). In exams, write repeated images only once.
Why this answer is correct
The correct answer is A. ({0,1,4}). (f(-1)=1), (f(0)=0), (f(1)=1), and (f(2)=4), so the range is ({0,1,4}). In exams, write repeated images only once.
Exam Tip
(f(-1)=1), (f(0)=0), (f(1)=1) और (f(2)=4), इसलिए परिसर ({0,1,4}) है। परीक्षा में दोहराई छवि को एक बार लिखें।
