यदि (f(x)=x-2-4) और (g(x)=\sqrt{x-2}) हों, तो (\left\(\frac{f}{g}\right\)(x)) का प्रांत क्या है?
If (f(x)=x-2-4) and (g(x)=\sqrt{x-2}), what is the domain of (\left\(\frac{f}{g}\right\)(x))?
Explanation opens after your attempt
A. ( \(2,\infty\) )
Concept
The denominator is \(\sqrt{x-2}\), so (x-2>0). In a quotient, the denominator cannot be zero.
Why this answer is correct
The correct answer is A. ( \(2,\infty\) ). The denominator is \(\sqrt{x-2}\), so (x-2>0). In a quotient, the denominator cannot be zero.
Exam Tip
भाजक \(\sqrt{x-2}\) है, इसलिए (x-2>0) चाहिए। भागफल में हर शून्य नहीं हो सकता।
