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
Correct Answer

A. \(\mathbb{R}-{-2})

Step 1

Concept

The denominator is (g(x)=x+2), so \(x\ne -2\). The numerator is always defined, so only the denominator restriction applies.

Step 2

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.

Step 3

Exam Tip

हर (g(x)=x+2) है, इसलिए \(x\ne -2\)। अंश हमेशा परिभाषित है इसलिए केवल हर का प्रतिबंध लगेगा।
