फलन (f(x)=\frac{2}{x-2+4}+3) की रेंज क्या है?
What is the range of (f(x)=\frac{2}{x-2+4}+3)?
Explanation opens after your attempt
A. ( \(3,\frac{7}{2}]\)
Concept
The range of \(\frac{2}{x^2+4}\) is ( \(0,\frac{1}{2}]\), so adding (3) gives ( \(3,\frac{7}{2}]\). In exams apply the vertical shift to the range.
Why this answer is correct
The correct answer is A. ( \(3,\frac{7}{2}]\). The range of \(\frac{2}{x^2+4}\) is ( \(0,\frac{1}{2}]\), so adding (3) gives ( \(3,\frac{7}{2}]\). In exams apply the vertical shift to the range.
Exam Tip
\(\frac{2}{x^2+4}\) की रेंज ( \(0,\frac{1}{2}]\) है, इसलिए (3) जोड़ने पर ( \(3,\frac{7}{2}]\) मिलेगा। परीक्षा में रेंज पर vertical shift लगाएं।
