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
Correct Answer

A. \(x^2+2x+1\)

Step 1

Concept

((f+g)(x)=x-2+1+2x=x-2+2x+1). Changing the order of terms does not change the value.

Step 2

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.

Step 3

Exam Tip

((f+g)(x)=x-2+1+2x=x-2+2x+1)। पदों का क्रम बदलने से मान नहीं बदलता।
