यदि (f(x)=\frac{2x}{x-2-1}) और (g(x)=\frac{1}{x-1}+\frac{1}{x+1}) हैं, तो (f-g) का डोमेन क्या होगा?
If (f(x)=\frac{2x}{x-2-1}) and (g(x)=\frac{1}{x-1}+\frac{1}{x+1}), what is the domain of (f-g)?
Explanation opens after your attempt
A. \( \mathbb{R}-{-1,1} \)
Concept
In both functions, (x=-1) and (x=1) are not allowed. Hence the domain of (f-g) is \( \mathbb{R}-{-1,1} \).
Why this answer is correct
The correct answer is A. \( \mathbb{R}-{-1,1} \). In both functions, (x=-1) and (x=1) are not allowed. Hence the domain of (f-g) is \( \mathbb{R}-{-1,1} \).
Exam Tip
दोनों फलनों में (x=-1) और (x=1) अनुमत नहीं हैं। इसलिए (f-g) का डोमेन \( \mathbb{R}-{-1,1} \) है।
