**Linear Algebra - Basis and Linear Transformation**

Consider the polynomial vector spaces \( P_2 \) and \( P_3 \).

Let \( B = \{x^2 + 2, x^2 - 4x + 7, -x + 1\} \) be a basis for \( P_2 \) and let \( B' = \{x^3 + x^2, x^3 + x^2 + x, x + 1, x^3 + 1\} \) be a basis for \( P_3 \).

We are given the linear transformation \( T: P_3 \to P_2 \) defined by:

\[ T(p(x)) = (x + 1)p(x) + p'(1) + \int_{0}^{3x} 2p(t) \, dt. \]

The task is to find \([T]_{B'}^B\), the matrix representation of \( T \) with respect to the basis \( B \) of \( P_2 \) and the basis \( B' \) of \( P_3 \).

**Steps to Determine the Matrix Representation:**

1. **Express \( T \) in Terms of Basis Elements:**
    - Compute \( T \) for each basis element in \( B' \).
    - Express the results as linear combinations of the basis elements in \( B \).

2. **Construct the Matrix:**
    - The coefficients obtained from expressing \( T \) basis elements in terms of \( B \) will form the columns of the matrix \([T]_{B'}^B\).

3. **Compile the Results:**
    - Ensure each column corresponds to the transformation of each corresponding basis element of \( B' \).

By following these steps, you will be able to find the matrix representation of the linear transformation \( T \).
