यदि (f(x)=x-4) और (g(x)=x-2+2x) हों, तो ((g+f)(x)) क्या है?

If (f(x)=x-4) and (g(x)=x-2+2x), what is ((g+f)(x))?

Explanation opens after your attempt
Correct Answer

A. \(x^2+3x-4\)

Step 1

Concept

((g+f)(x)=g(x)+f(x)=x-2+2x+x-4=x-2+3x-4). In addition, changing the order does not change the answer.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+3x-4\). ((g+f)(x)=g(x)+f(x)=x-2+2x+x-4=x-2+3x-4). In addition, changing the order does not change the answer.

Step 3

Exam Tip

((g+f)(x)=g(x)+f(x)=x-2+2x+x-4=x-2+3x-4)। addition में order बदलने से answer नहीं बदलता।
