**Problem 4:**

Let \( B = \left\{ \begin{pmatrix} 1 \\ 2 \end{pmatrix}, \begin{pmatrix} 2 \\ 5 \end{pmatrix} \right\} \) be a basis of \( \mathbb{R}^2 \). The linear transformation \( T: \mathbb{R}^2 \rightarrow \mathbb{R}^2 \) is given by \( T\v = A\v \), where \( A \) is a matrix.

The matrix \( A \) is given by:

\[
A = \begin{bmatrix} 2 & 3 \\ 0 & 2 \end{bmatrix}
\]

Tasks:

(a) Use the definition to find \([T]^B_B\), the matrix of \( T \) under the basis \( B \).

(b) Use the definition to find \([T]^E_E\), the matrix of \( T \) under the standard basis \( E \).

(c) Compute \( P_{E \leftarrow B} \) and \( P_{B \leftarrow E} \).

(d) Use Parts (b) and (c) to find \([T]^B_B\), the matrix of \( T \) under the basis \( B \). Compare your answer with that of Part (a).
