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
A. \(-3 \leq x \leq 3\)
Concept
For the square root, \(9-x^2 \geq 0\), so \(-3 \leq x \leq 3\). The linear function gives no extra restriction.
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.
Exam Tip
वर्गमूल के लिए \(9-x^2 \geq 0\), इसलिए \(-3 \leq x \leq 3\)। रैखिक फलन कोई अतिरिक्त प्रतिबंध नहीं देता।
