यदि (f(x)=x-2) और (g(x)=4) हैं, तो \(\frac{f}{g}\) का परास क्या है?
If (f(x)=x-2) and (g(x)=4), what is the range of \(\frac{f}{g}\)?
Explanation opens after your attempt
Correct Answer
A. \([0,\infty\))
Concept
\(\frac{f}{g}=\frac{x^2}{4}\) and \(x^2\ge 0\), so the range is \([0,\infty\)). Division by a positive constant does not change sign.
Why this answer is correct
The correct answer is A. \([0,\infty\)). \(\frac{f}{g}=\frac{x^2}{4}\) and \(x^2\ge 0\), so the range is \([0,\infty\)). Division by a positive constant does not change sign.
Exam Tip
\(\frac{f}{g}=\frac{x^2}{4}\) और \(x^2\ge 0\), इसलिए परास \([0,\infty\)) है। धन स्थिर से भाग देने पर चिन्ह नहीं बदलता।
