फलन (f(x)=\frac{1}{x-2+4}) का परिसर ज्ञात कीजिए।
Find the range of (f(x)=\frac{1}{x-2+4}).
Explanation opens after your attempt
A. (\(0,\frac{1}{4}]\)
Concept
Since \(x^2+4\ge 4\), (0<f(x)\le \frac{1}{4}). The value (0) is never attained.
Why this answer is correct
The correct answer is A. (\(0,\frac{1}{4}]\). Since \(x^2+4\ge 4\), (0<f(x)\le \frac{1}{4}). The value (0) is never attained.
Exam Tip
क्योंकि \(x^2+4\ge 4\), इसलिए (0<f(x)\le \frac{1}{4})। शून्य प्राप्त नहीं होता।
