फलन (f(x)=\sqrt{25-x-2}) का प्रांत चुनिए।

Choose the domain of (f(x)=\sqrt{25-x-2}).

Explanation opens after your attempt
Correct Answer

A. ([-5,5])

Step 1

Concept

Here \(25-x^2\ge 0\), so \(x^2\le 25\) and \(x\in[-5,5]\). In such questions, solve the inequality carefully.

Step 2

Why this answer is correct

The correct answer is A. ([-5,5]). Here \(25-x^2\ge 0\), so \(x^2\le 25\) and \(x\in[-5,5]\). In such questions, solve the inequality carefully.

Step 3

Exam Tip

यहां \(25-x^2\ge 0\), इसलिए \(x^2\le 25\) और \(x\in[-5,5]\)। ऐसे प्रश्नों में असमानता को सावधानी से हल करें।
