What is the range of (f(x)=\frac{1}{x-9}+4)?फलन (f(x)=\frac{1}{x-9}+4) की रेंज क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (\mathbb{R}\setminus{4})(\mathbb{R}\setminus{4})
(\frac{1}{x-9}) is never (0), so output (4) cannot occur. In exams identify the excluded range value after a vertical shift.(\frac{1}{x-9}) कभी (0) नहीं होता, इसलिए (4) output नहीं बन सकता। परीक्षा में vertical shift से excluded range value पहचानें।
