यदि (f(x)=\frac{x-3}{x+3}) और (g(x)=\frac{x+3}{x-3}) हैं, तो ((f+g)(3)) के बारे में सही कथन क्या है?
If (f(x)=\frac{x-3}{x+3}) and (g(x)=\frac{x+3}{x-3}), which statement about ((f+g)(3)) is correct?
Explanation opens after your attempt
Correct Answer
A. अपरिभाषितUndefined
Concept
The denominator of (g(x)) is (x-3), so at (x=3), (g) and (f+g) are undefined. In a sum, both functions must be defined.
Why this answer is correct
The correct answer is A. अपरिभाषित / Undefined. The denominator of (g(x)) is (x-3), so at (x=3), (g) and (f+g) are undefined. In a sum, both functions must be defined.
Exam Tip
(g(x)) में हर (x-3) है, इसलिए (x=3) पर (g) और (f+g) अपरिभाषित हैं। योग में दोनों फलन परिभाषित होने चाहिए।
