यदि (f(x)=\frac{x}{x+1}) और (g(x)=\frac{1}{x-2}) हैं, तो ((f+g)(x)) का डोमेन क्या है?
If (f(x)=\frac{x}{x+1}) and (g(x)=\frac{1}{x-2}), what is the domain of ((f+g)(x))?

Correct Answer
A. \( \mathbb{R}-{-1,2} \)
Concept
The first function needs \(x\neq-1\), and the second needs \(x\neq2\). The domain of the sum is the common part of these conditions.
Why this answer is correct
The correct answer is A. \( \mathbb{R}-{-1,2} \). The first function needs \(x\neq-1\), and the second needs \(x\neq2\). The domain of the sum is the common part of these conditions.
Exam Tip
पहले फलन में \(x\neq-1\) और दूसरे में \(x\neq2\) चाहिए। जोड़ का डोमेन इन दोनों शर्तों का साझा भाग है।
