यदि (f(x)=x-2+1) और (g(x)=x-2-1) हों, तो ((f-g)(x)) क्या होगा?
If (f(x)=x-2+1) and (g(x)=x-2-1), what is ((f-g)(x))?
Explanation opens after your attempt
Correct Answer
A. (2)
Concept
((f-g)(x)=x-2+1-\(x^2-1\)=2). While removing the bracket, the sign of (-1) changes to (+1).
Why this answer is correct
The correct answer is A. (2). ((f-g)(x)=x-2+1-\(x^2-1\)=2). While removing the bracket, the sign of (-1) changes to (+1).
Exam Tip
((f-g)(x)=x-2+1-\(x^2-1\)=2)। bracket हटाते समय (-1) का sign बदलकर (+1) होता है।
