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
Correct Answer

A. ({0,2,12})

Step 1

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.

Step 2

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.

Step 3

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।
