**Exercise 10.1.2**  
Consider the following functions \( T: \mathbb{R}^3 \rightarrow \mathbb{R}^2 \). For each function \( T \), show that \( T \) is a linear transformation. Do this by showing that \( T \) is a matrix transformation, i.e., find a matrix \( A \) such that \( T(\mathbf{v}) = A\mathbf{v} \).

(a) \( T \left( \begin{bmatrix} x \\ y \\ z \end{bmatrix} \right) = \begin{bmatrix} x + 2y + 3z \\ 2y - 3x + z \end{bmatrix} \).

(b) \( T \left( \begin{bmatrix} x \\ y \\ z \end{bmatrix} \right) = \begin{bmatrix} 7x + 2y + z \\ 3x - 11y + 2z \end{bmatrix} \).

(c) \( T \left( \begin{bmatrix} x \\ y \\ z \end{bmatrix} \right) = \begin{bmatrix} 3x + 2y + z \\ x + 2y + 6z \end{bmatrix} \).

(d) \( T \left( \begin{bmatrix} x \\ y \\ z \end{bmatrix} \right) = \begin{bmatrix} 2y - 5x + z \\ x + y + z \end{bmatrix} \).
