Question
Let \( A = \begin{bmatrix} 4 & 0 \\ 0 & 4 \end{bmatrix} \), and define \( T: \mathbb{R}^2 \rightarrow \mathbb{R}^2 \) by \( T(\mathbf{x}) = A\mathbf{x} \). Find the images under \( T \) of \( \mathbf{u} = \begin{bmatrix} 4 \\ -3 \end{bmatrix} \) and \( \mathbf{v} = \begin{bmatrix} a \\ b \end{bmatrix} \).

\[ T(\mathbf{u}) = \boxed{\phantom{\text{answer}}} \]
