यदि (f(x)=x-2+2) और (g(x)=x-1), तो (\(f\circ g\)(x)) तथा (\(g\circ f\)(x)) के बारे में सही कथन कौन-सा है?
If (f(x)=x-2+2) and (g(x)=x-1), which statement about (\(f\circ g\)(x)) and (\(g\circ f\)(x)) is correct?
Explanation opens after your attempt
A. दोनों सामान्यतः समान नहीं हैंThey are generally not equal
Concept
(\(f\circ g\)(x)=f(x-1)=(x-1)2+2).
Why this answer is correct
(\(g\circ f\)(x)=g\(x^2+2\)=x-2+1).
Exam Tip
The expressions are generally different, so order is important in composition. चरण 1: (\(f\circ g\)(x)=f(x-1)=(x-1)2+2)। चरण 2: (\(g\circ f\)(x)=g\(x^2+2\)=x-2+1)। चरण 3: दोनों व्यंजक सामान्यतः अलग हैं, इसलिए संयुक्त फलन में क्रम महत्वपूर्ण है।
