यदि (f(x)=2x+1) और (g(x)=x-2) हैं तो (\(g\circ f\)(x)) क्या है?

If (f(x)=2x+1) and (g(x)=x-2) then what is (\(g\circ f\)(x))?

Explanation opens after your attempt
Correct Answer

A. \(4x^2+4x+1\)

Step 1

Concept

(\(g\circ f\)(x)=g(f(x))=(2x+1)2=4x-2+4x+1). Expand ((a+b)2) correctly.

Step 2

Why this answer is correct

The correct answer is A. \(4x^2+4x+1\). (\(g\circ f\)(x)=g(f(x))=(2x+1)2=4x-2+4x+1). Expand ((a+b)2) correctly.

Step 3

Exam Tip

(\(g\circ f\)(x)=g(f(x))=(2x+1)2=4x-2+4x+1)। ((a+b)2) का विस्तार सही करें।
