फलन (f(x)=\frac{1}{\sqrt{x-2-25}}) का डोमेन क्या है?
What is the domain of (f(x)=\frac{1}{\sqrt{x-2-25}})?
Explanation opens after your attempt
A. (\(-\infty,-5\)\cup\(5,\infty\))
Concept
The square root is in the denominator, so \(x^2-25>0\) is required. In exams do not include equality for a denominator square root.
Why this answer is correct
The correct answer is A. (\(-\infty,-5\)\cup\(5,\infty\)). The square root is in the denominator, so \(x^2-25>0\) is required. In exams do not include equality for a denominator square root.
Exam Tip
हर में वर्गमूल है इसलिए \(x^2-25>0\) चाहिए। परीक्षा में हर वाले वर्गमूल के लिए बराबरी शामिल न करें।
