यदि \(f:A\to\mathbb{R}\), \(A=\{-2,0,3\}\), और (f(x)=x-2+x) है, तो रेंज क्या है?
If \(f:A\to\mathbb{R}\), \(A=\{-2,0,3\}\), and (f(x)=x-2+x), what is the range?
Explanation opens after your attempt
A. ({0,2,12})
Concept
The values are (f(-2)=2), (f(0)=0), and (f(3)=12). In exams find the image of every input in a finite domain.
Why this answer is correct
The correct answer is A. ({0,2,12}). The values are (f(-2)=2), (f(0)=0), and (f(3)=12). In exams find the image of every input in a finite domain.
Exam Tip
इनपुट पर वैल्यू (f(-2)=2), (f(0)=0), (f(3)=12) हैं। परीक्षा में finite domain में हर input की image निकालें।
