Answer
A=$\left[\begin{array}{lll}
0 & 2 & 3\\
1 & 1 & -2\\
4 & 1 & 0\\
3 & -1 & -1
\end{array}\right]$
Work Step by Step
The given set, $W\subset \mathbb{R}^{4}$.
x$\in$W $\Rightarrow$ x$=r\left[\begin{array}{l}
0\\
1\\
4\\
3
\end{array}\right]+s\left[\begin{array}{l}
2\\
1\\
1\\
-1
\end{array}\right]+t\left[\begin{array}{l}
3\\
-2\\
0\\
-1
\end{array}\right]$
By definition, on p.203
The column space of an m$\times$n matrix A, written as Col A, is the set of all linear combinations of the columns of A.
$W=$Col A, where
A=$\left[\begin{array}{lll}
0 & 2 & 3\\
1 & 1 & -2\\
4 & 1 & 0\\
3 & -1 & -1
\end{array}\right]$
