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