यदि \(f:\mathbb{R}-{-2}\to\mathbb{R}\) को (f(x)=\frac{x-2+4x+4}{x+2}) से दिया गया है, तो (f) का परिसर क्या है?
If \(f:\mathbb{R}-{-2}\to\mathbb{R}\) is given by (f(x)=\frac{x-2+4x+4}{x+2}), what is the range of (f)?
Explanation opens after your attempt
Correct Answer
B. \(\mathbb{R}-{0}\)
Concept
On the given domain (f(x)=x+2), but removing (x=-2) removes the value (0). After simplification, note the image of the excluded input.
Why this answer is correct
The correct answer is B. \(\mathbb{R}-{0}\). On the given domain (f(x)=x+2), but removing (x=-2) removes the value (0). After simplification, note the image of the excluded input.
Exam Tip
दिए गए प्रांत पर (f(x)=x+2) है लेकिन (x=-2) हटने से मान (0) नहीं मिलता। सरलीकरण के बाद हटे इनपुट की छवि ध्यान रखें।
