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
A. \(4x^2+8x+4\)
Concept
First apply (f(x)=x+1).
Why this answer is correct
Then (g(f(x))=2(x+1)=2x+2).
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)।
