**Problem Statement:**

Find the change of basis matrix \([ \mathcal{E} ]_{\mathcal{B}}\) and use it to compute \([ \mathbf{v} ]_{\mathcal{B}}\).

**Given Data:**

- Basis \(\mathcal{B}\) is given as:
  \[
  \mathcal{B} = \left\{ 
  \begin{bmatrix} 
  7 \\ 
  1 \\ 
  2 
  \end{bmatrix}, 
  \begin{bmatrix} 
  2 \\ 
  -2 \\ 
  4 
  \end{bmatrix}, 
  \begin{bmatrix} 
  0 \\ 
  -2 \\ 
  4 
  \end{bmatrix} 
  \right\}
  \]

- Vector \(\mathbf{v}\) is given as:
  \[
  \mathbf{v} = 
  \begin{bmatrix} 
  -17 \\ 
  -71 \\ 
  114 
  \end{bmatrix}
  \]

**Tasks:**

1. Determine the matrix \([ \mathcal{E} ]_{\mathcal{B}}\).
2. Use this matrix to calculate \([ \mathbf{v} ]_{\mathcal{B}}\).

**Solution:**

- \([ \mathcal{E} ]_{\mathcal{B}} = \) [Enter the change of basis matrix here]

- \([ \mathbf{v} ]_{\mathcal{B}} = \) [Enter the coordinates of the vector in the new basis here]
