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

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

Explanation opens after your attempt
Correct Answer

A. \(4x^2+8x+4\)

Step 1

Concept

First apply (f(x)=x+1).

Step 2

Why this answer is correct

Then (g(f(x))=2(x+1)=2x+2).

Step 3

Exam Tip

Finally (h(2x+2)=(2x+2)2=4x-2+8x+4). चरण 1: पहले (f(x)=x+1) लगाएँ। चरण 2: फिर (g(f(x))=2(x+1)=2x+2)। चरण 3: अंत में (h(2x+2)=(2x+2)2=4x-2+8x+4)।
