Question
Let \( T : \mathbb{R}^3 \rightarrow \mathbb{R}^2 \) be defined by 

\[
T \begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix} = \begin{bmatrix} -2x_1 \\ 2x_2 + x_3 \end{bmatrix}.
\]

Let \( \mathcal{B} = \left\{ \mathbf{u}_1 = \begin{bmatrix} -1 \\ -7 \\ 4 \end{bmatrix}, \mathbf{u}_2 = \begin{bmatrix} 3 \\ 1 \\ -5 \end{bmatrix}, \mathbf{u}_3 = \begin{bmatrix} -4 \\ 0 \\ -3 \end{bmatrix} \right\} \) 

and 

\(\mathcal{C} = \left\{ \mathbf{v}_1 = \begin{bmatrix} -7 \\ 6 \end{bmatrix}, \mathbf{v}_2 = \begin{bmatrix} 0 \\ 1 \end{bmatrix} \right\}. \)

What augmented matrix should be used to find \([ T ]_{\mathcal{C}}^{\mathcal{B}}\), the matrix representation of \( T \) with respect to the bases \(\mathcal{B}\) and \(\mathcal{C}\).

\[
\begin{bmatrix}
\text{Ex: 5} & & \\
& & \\
& & 
\end{bmatrix}
