![The image shows a mathematical problem involving matrix transformations. Here is the transcription:
---
**Problem:**
Let
\[ A = \begin{bmatrix} 1 & 0 \\ -3 & 2 \\ 0 & 1 \end{bmatrix} \]
and define \( T: \mathbb{R}^2 \rightarrow \mathbb{R}^2 \) by \( T(\vec{x}) = A \vec{x} \).
Find \( T\left(\begin{bmatrix} -4 \\ 2 \end{bmatrix}\right) \).
---
Below the problem, there are two buttons labeled "Calculator" and "Check Answer".
**Explanation:**
- A matrix \( A \) is given, which is a 3x2 matrix in this example, implying the problem might have a typographical error since typically \( T: \mathbb{R}^n \rightarrow \mathbb{R}^m \) would require a compatible matrix format.
- The map \( T \) is defined as a linear transformation that multiplies a given vector \( \vec{x} \) by the matrix \( A \).
- The task is to compute the transformation of the vector \(\begin{bmatrix} -4 \\ 2 \end{bmatrix}\) under this mapping.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2a87bda2-77ee-4643-b996-8126adae9acf%2F3100df06-04a6-4723-97ff-413cf7e7dfb7%2Fm6yb12f_processed.jpeg&w=3840&q=75)
