यदि (f(x)=\sqrt{4-x-2}) और (g(x)=x+1) हैं तो ((fg)(x)) का प्रांत क्या है?

If (f(x)=\sqrt{4-x-2}) and (g(x)=x+1) then what is the domain of ((fg)(x))?

Explanation opens after your attempt
Correct Answer

A. \([-2,2])

Step 1

Concept

For the square root \(4-x^2\ge 0\), that is \(-2\le x\le 2\). The function (g(x)) is defined for all real (x).

Step 2

Why this answer is correct

The correct answer is A. \([-2,2]). For the square root \(4-x^2\ge 0\), that is \(-2\le x\le 2\). The function (g(x)) is defined for all real (x).

Step 3

Exam Tip

वर्गमूल के लिए \(4-x^2\ge 0\), यानी \(-2\le x\le 2\)। (g(x)) सभी वास्तविक (x) पर परिभाषित है।
