Question
**Problem 7**: The standard matrix for a linear transformation \( T: \mathbb{R}^3 \to \mathbb{R}^3 \) is 

\[
\begin{bmatrix}
-1 & 2 & 1 \\
0 & 1 & 3 \\
1 & -1 & 1
\end{bmatrix}
\]

Use the change-of-basis formula to find its matrix with respect to the basis 

\[
\mathcal{B} = \left\{
\begin{bmatrix}
1 \\
0 \\
-1
\end{bmatrix}, 
\begin{bmatrix}
0 \\
2 \\
3
\end{bmatrix}, 
\begin{bmatrix}
1 \\
1 \\
1
\end{bmatrix}
\right\}.
\]

**Explanation:**

You are given a standard matrix for a linear transformation in \(\mathbb{R}^3\) and asked to find its representation with respect to a new basis \(\mathcal{B}\). This involves utilizing the change-of-basis formula, which is a fundamental concept in linear algebra used to transform matrix representations from one basis to another.
