यदि \(f:\mathbb{R}\to\mathbb{R}\) और \(g:\mathbb{R}\to\mathbb{R}\) के लिए (f(x)=x+2) तथा (g(x)=x-2), तो (\(g\circ f\)(-3)) का मान क्या है?
If \(f:\mathbb{R}\to\mathbb{R}\) and \(g:\mathbb{R}\to\mathbb{R}\) are given by (f(x)=x+2) and (g(x)=x-2), what is the value of (\(g\circ f\)(-3))?

A. (1)
Concept
पहले (f(-3)) निकालें, (f(-3)=-1)। / First find (f(-3)), which is (-1).
Why this answer is correct
अब (g(-1)=(-1)2=1)। / Then compute (g(-1)=(-1)2=1).
Exam Tip
संयुक्त फलन में दाएँ वाले फलन को पहले लगाएँ। / In composition, apply the right-side function first.
