Let's break down the tasks presented in the image:

We are given two bases for the vector space \( V^3 \):
1. Basis (I): \( \{x_1, x_2, x_3\} \)
2. Basis (II): \( \{y_1, y_2, y_3\} \)

The transition matrix \( C \) from Basis (I) to Basis (II) is:

\[
C = \begin{pmatrix}
1 & 0 & 1 \\
0 & -1 & 0 \\
-1 & 0 & 1
\end{pmatrix}
\]

A linear transformation \( T \) is given that satisfies the following conditions:

\[
T(x_1 + 2x_2 + 3x_3) = y_1 + y_2
\]
\[
T(2x_1 + x_2 + 2x_3) = y_2 + y_3
\]
\[
T(x_1 + 3x_2 + 4x_3) = y_1 + y_3
\]

The problem asks us to:

1. Find the matrix \( D \) of \( T \) with respect to Basis (II).
2. Find the coordinates of \( T(y_1) \) in terms of Basis (I).

### Solution:

#### 1. Finding the Matrix \( D \) of \( T \) in Basis (II):
To find the matrix \( D \), we will express how \( T \) transforms each vector from Basis (I) to Basis (II). 

Let's represent the transformation rules given by \( T \) in matrix form:
- First, express each transformation equation in matrix form using the coordinates relative to \( x_1, x_2, x_3 \).
- Then, solve for the corresponding matrix \( D \).

#### 2. Finding \( T(y_1) \) in Basis (I):
We need to express \( T(y_1) \) in terms of the original Basis (I). This will involve:
- Applying the inverse of the transition matrix \( C \) to express \( y_1 \) in terms of \( x_1, x_2, x_3 \).
- Applying \( T \) to these coordinates to get the result.
