यदि (f(x)=x-2+4x+5) और (g(x)=x+2) हैं तो (\left\(\frac{f}{g}\right\)(x)) का प्रांत क्या है?
If (f(x)=x-2+4x+5) and (g(x)=x+2) then what is the domain of (\left\(\frac{f}{g}\right\)(x))?
Explanation opens after your attempt
A. \(\mathbb{R}-{-2})
Concept
The denominator is (g(x)=x+2), so \(x\ne -2\). The numerator is always defined, so only the denominator restriction applies.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{-2}). The denominator is (g(x)=x+2), so \(x\ne -2\). The numerator is always defined, so only the denominator restriction applies.
Exam Tip
हर (g(x)=x+2) है, इसलिए \(x\ne -2\)। अंश हमेशा परिभाषित है इसलिए केवल हर का प्रतिबंध लगेगा।
