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

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

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

((f+g)(x)=f(x)+g(x)), so \(2x+3+x^2-1=x^2+2x+2\). In exams, combine like terms carefully.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+2x+2\). ((f+g)(x)=f(x)+g(x)), so \(2x+3+x^2-1=x^2+2x+2\). In exams, combine like terms carefully.

Step 3

Exam Tip

((f+g)(x)=f(x)+g(x)), इसलिए \(2x+3+x^2-1=x^2+2x+2\)। परीक्षा में like terms को साथ जोड़ें।
