यदि (f(x)=\sqrt{9-x-2}) और (g(x)=x+1) हैं, तो ((f+g)(x)) का प्रांत क्या है?

If (f(x)=\sqrt{9-x-2}) and (g(x)=x+1), what is the domain of ((f+g)(x))?

Explanation opens after your attempt
Correct Answer

A. \(-3 \leq x \leq 3\)

Step 1

Concept

For the square root, \(9-x^2 \geq 0\), so \(-3 \leq x \leq 3\). The linear function gives no extra restriction.

Step 2

Why this answer is correct

The correct answer is A. \(-3 \leq x \leq 3\). For the square root, \(9-x^2 \geq 0\), so \(-3 \leq x \leq 3\). The linear function gives no extra restriction.

Step 3

Exam Tip

वर्गमूल के लिए \(9-x^2 \geq 0\), इसलिए \(-3 \leq x \leq 3\)। रैखिक फलन कोई अतिरिक्त प्रतिबंध नहीं देता।
