**Matrix Representation of a Linear Transformation**

This exercise involves completing the matrix representation for the linear transformation \( T : P_2 \rightarrow P_2 \), which acts on polynomials of degree 2 or less.

### Given Transformation

The linear transformation \( T \) is defined as:

\[
T(ax^2 + bx + c) = (-3a + 7b + 3c)x^2 + (2a + 7b + 5c)x + (4a - 2b + 2c)
\]

### Matrix Representation

To find the matrix form of \( T \), express the transformation as a matrix multiplication:

\[
T \left( \begin{bmatrix} a \\ b \\ c \end{bmatrix} \right) = \begin{bmatrix}
\text{[Ex: 5]} & & \\
& & \\
& & 
\end{bmatrix}
\begin{bmatrix}
a \\ b \\ c
\end{bmatrix}
\]

#### Explanation of Entries

- Each input polynomial \( ax^2 + bx + c \) is mapped to a new polynomial by calculating the coefficients of \( x^2 \), \( x \), and the constant term.
- The matrix to be filled corresponds to these transformations whereby the entries will reflect coefficients that multiply \( a \), \( b \), and \( c \) in each term of \( T \).

This exercise requires completing the empty cells to form the correct transformation matrix that encodes the given polynomial transformation rules.
