Chapter 6.3, Problem 10P

In each of problems $9$ through $12$, solve the given initial value problem and plot the graph of the solution in ${\text{R}}^{\text{3}}$. Describe the behavior of the solution as $t\to \infty$.

$\text{x'=}\left(\begin{array}{ccc}0& 0& -1\\ 2& 0& 0\\ -1& 2& 4\end{array}\right)\text{x,}\text{x}\left(0\right)=\left(\begin{array}{c}7\\ 5\\ 5\end{array}\right)$
