यदि (f(x)=x-1) और (g(x)=\frac{1}{x-1}) हैं, तो ((f+g)(2)) का मान क्या है?
If (f(x)=x-1) and (g(x)=\frac{1}{x-1}), what is the value of ((f+g)(2))?
Explanation opens after your attempt
A. (2)
Concept
(f(2)=1) and (g(2)=1), so the sum is (2). Here (x=1) is excluded, but (x=2) is valid.
Why this answer is correct
The correct answer is A. (2). (f(2)=1) and (g(2)=1), so the sum is (2). Here (x=1) is excluded, but (x=2) is valid.
Exam Tip
(f(2)=1) और (g(2)=1), इसलिए योग (2) है। यहाँ (x=1) निषिद्ध है, पर (x=2) मान्य है।
