फलन \(y=\frac{1}{x^2+4}\) के ग्राफ की रेंज क्या है?
What is the range of \(y=\frac{1}{x^2+4}\)?
Explanation opens after your attempt
A. (\(0,\frac{1}{4}]\)
Concept
Since \(x^2+4\ge 4\), the maximum value is \(\frac{1}{4}\). The graph approaches (0) but never takes (0).
Why this answer is correct
The correct answer is A. (\(0,\frac{1}{4}]\). Since \(x^2+4\ge 4\), the maximum value is \(\frac{1}{4}\). The graph approaches (0) but never takes (0).
Exam Tip
\(x^2+4\ge 4\) इसलिए अधिकतम मान \(\frac{1}{4}\) है। ग्राफ (0) के पास जाता है पर (0) नहीं लेता।
