यदि (f(x)=x-2) और (g(x)=x+2), तो (\(f\circ g\)(x)) और (\(g\circ f\)(x)) के बारे में सही कथन क्या है?
If (f(x)=x-2) and (g(x)=x+2), which statement about (\(f\circ g\)(x)) and (\(g\circ f\)(x)) is correct?
Explanation opens after your attempt
C. (\(g\circ f\)(x)=x-2+2)
Concept
(\(f\circ g\)(x)=f(x+2)=(x+2)2).
Why this answer is correct
(\(g\circ f\)(x)=g\(x^2\)=x-2+2).
Exam Tip
Composition of functions is generally not commutative. चरण 1: (\(f\circ g\)(x)=f(x+2)=(x+2)2)। चरण 2: (\(g\circ f\)(x)=g\(x^2\)=x-2+2)। चरण 3: संयुक्त फलन सामान्यतः क्रमविनिमेय नहीं होता।
