यदि (f(x)=\frac{x}{x-2-4}) और (g(x)=\frac{1}{x-2}) हैं, तो ((f+g)(x)) का प्रांत क्या है?
If (f(x)=\frac{x}{x-2-4}) and (g(x)=\frac{1}{x-2}), what is the domain of ((f+g)(x))?
Explanation opens after your attempt
A. \(\mathbb{R}\setminus{-2,2}\)
Concept
(x-2-4=(x-2)(x+2)), so (x=2) and (x=-2) are forbidden. For a sum, take the intersection of the domains.
Why this answer is correct
The correct answer is A. \(\mathbb{R}\setminus{-2,2}\). (x-2-4=(x-2)(x+2)), so (x=2) and (x=-2) are forbidden. For a sum, take the intersection of the domains.
Exam Tip
(x-2-4=(x-2)(x+2)), इसलिए (x=2) और (x=-2) निषिद्ध हैं। योग में दोनों फलनों के प्रांत का प्रतिच्छेद लें।
