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
Correct Answer

A. (\(-\infty,-5\)\cup\(5,\infty\))

Step 1

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.

Step 2

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.

Step 3

Exam Tip

हर में वर्गमूल है इसलिए \(x^2-25>0\) चाहिए। परीक्षा में हर वाले वर्गमूल के लिए बराबरी शामिल न करें।
