फलन (f(x)=\sqrt{16-x-2}) का वास्तविक डोमेन क्या है?

What is the real domain of (f(x)=\sqrt{16-x-2})?

Explanation opens after your attempt
Correct Answer

A. ([-4,4])

Step 1

Concept

For a real square root, \(16-x^2\ge 0\) is required. This gives \(x^2\le 16\) and the domain ([-4,4]).

Step 2

Why this answer is correct

The correct answer is A. ([-4,4]). For a real square root, \(16-x^2\ge 0\) is required. This gives \(x^2\le 16\) and the domain ([-4,4]).

Step 3

Exam Tip

वास्तविक वर्गमूल के लिए \(16-x^2\ge 0\) चाहिए। इससे \(x^2\le 16\) और डोमेन ([-4,4]) मिलता है।
