यदि (f(x)=3x-2) और (g(x)=2x+1) हों, तो ((f+2g)(x)) क्या है?

If (f(x)=3x-2) and (g(x)=2x+1), what is ((f+2g)(x))?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

((f+2g)(x)=f(x)+2g(x)=3x-2+2(2x+1)). First multiply, then add.

Step 2

Why this answer is correct

The correct answer is A. \(3x^2+4x+2\). ((f+2g)(x)=f(x)+2g(x)=3x-2+2(2x+1)). First multiply, then add.

Step 3

Exam Tip

((f+2g)(x)=f(x)+2g(x)=3x-2+2(2x+1))। पहले गुणा करें, फिर जोड़ें।
