**Consider the system of equations:**

\[ 
\mathbf{x}' = \begin{pmatrix} 1 & 1 & 3 \\ 1 & 3 & 1 \\ 3 & 1 & 1 \end{pmatrix} \mathbf{x}.
\]

**Find a fundamental matrix for the given system of equations:**

\[ 
\Psi(t) = \begin{pmatrix}
-e^{-2t} & e^{2t} & e^{5t} \\
0 & -2e^{2t} & e^{5t} \\
e^{-2t} & e^{2t} & e^{5t} 
\end{pmatrix}
\]

*Note: The matrix \(\Psi(t)\) has a green check mark indicating it as correct.*

**Find the fundamental matrix \(\Phi(t)\) satisfying \(\Phi(0) = I\):**

\[ 
\Phi(t) = \begin{pmatrix}
1 & 0 & 0 \\
0 & 1 & 0 \\
0 & 0 & 1 
\end{pmatrix}
\]

*Note: The matrix \(\Phi(t)\) has a red cross mark indicating it is incorrect.*
