A. दोनों हमेशा समान नहीं हैंThey are not always equal
Concept
(\(f\circ g\)(x)=f(x+1)=(x+1)2)। / (\(f\circ g\)(x)=f(x+1)=(x+1)2).
Why this answer is correct
(\(g\circ f\)(x)=g\(x^2\)=x-2+1)। / (\(g\circ f\)(x)=g\(x^2\)=x-2+1).
Exam Tip
दोनों व्यंजक सामान्यतः समान नहीं हैं, इसलिए क्रम का ध्यान रखें। / These expressions are generally not equal, so order matters.
