If (f(x)=\frac{3}{x+1}-4), what is the range of (f(x))?यदि (f(x)=\frac{3}{x+1}-4) है, तो (f(x)) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\mathbb{R}\setminus{-4})(\mathbb{R}\setminus{-4})
(\frac{3}{x+1}) is never (0), so the output (-4) is not obtained. In exams a vertical shift changes the excluded range value.(\frac{3}{x+1}) कभी (0) नहीं होता, इसलिए (-4) आउटपुट नहीं मिलेगा। परीक्षा में vertical shift से excluded range value बदलती है।
