यदि (f(x)=x-2+1) और (g(x)=2x) हों, तो ((f+g)(x)) किसके बराबर है?
If (f(x)=x-2+1) and (g(x)=2x), which expression equals ((f+g)(x))?
Explanation opens after your attempt
A. \(x^2+2x+1\)
Concept
((f+g)(x)=x-2+1+2x=x-2+2x+1). Changing the order of terms does not change the value.
Why this answer is correct
The correct answer is A. \(x^2+2x+1\). ((f+g)(x)=x-2+1+2x=x-2+2x+1). Changing the order of terms does not change the value.
Exam Tip
((f+g)(x)=x-2+1+2x=x-2+2x+1)। पदों का क्रम बदलने से मान नहीं बदलता।
