यदि (f(x)=x-2+1) और (g(x)=x-2-1) हैं, तो ((f-g)(x)) का मान क्या है?
If (f(x)=x-2+1) and (g(x)=x-2-1), what is the value of ((f-g)(x))?
Explanation opens after your attempt
A. (2)
Concept
((f-g)(x)=x-2+1-\(x^2-1\)=2). While subtracting, signs change after opening brackets.
Why this answer is correct
The correct answer is A. (2). ((f-g)(x)=x-2+1-\(x^2-1\)=2). While subtracting, signs change after opening brackets.
