यदि (f(x)=\frac{x-2}{x+2}) और (g(x)=\frac{x+2}{x-2}) हैं तो ((f+g)(x)) का प्रांत क्या है?
If (f(x)=\frac{x-2}{x+2}) and (g(x)=\frac{x+2}{x-2}) then what is the domain of ((f+g)(x))?
Explanation opens after your attempt
Correct Answer
A. \(\mathbb{R}-{-2,2})
Concept
The first function needs \(x\ne -2\) and the second needs \(x\ne 2\). The domain of the sum is obtained by excluding both restrictions.
Why this answer is correct
The correct answer is A. \(\mathbb{R}-{-2,2}). The first function needs \(x\ne -2\) and the second needs \(x\ne 2\). The domain of the sum is obtained by excluding both restrictions.
Exam Tip
पहले फलन में \(x\ne -2\) और दूसरे में \(x\ne 2\) है। योग का प्रांत दोनों प्रतिबंधों को हटाकर मिलेगा।
