Answer & Solution

Correct Answer

(C)  \([0,1]\)

Step-by-step Solution

Detailed explanation

\(f(g(x))= \begin{cases}2+2 g(x) & ,-1 \leq g(x)<0 \\ 1-\frac{g(x)}{3}, & 0\leq g(x) \leq 3\end{cases}\) By \((1)\) \(x \in \phi\) And by \((2)\) \(x \in[-3,0]\) and \(x \in[0,1]\) Range of \(f(g(X))\) is \([0,1]\)
