Problem 11. (5 points) Let $v_1 = \begin{bmatrix} 0 \ -1 \ -3 \end{bmatrix}$ and $v_2 = \begin{bmatrix} -2 \ 3 \ 0 \end{bmatrix}$ be eigenvectors of the matrix $A$ which correspond to the eigenvalues $\lambda_1 = -2$ and $\lambda_2 = 2$, respectively. Let $v = -4v_1 + 2v_2$. Find $Av$. $Av = \begin{bmatrix} \Box \\ \Box \\ \Box \end{bmatrix}$ Note: You can earn partial credit on this problem.
