LINEAR ALGEBRA
(a) for what values of h is $\mathbf{v}_{3}$ is Span $\left\{\mathbf{v}_{1}, \mathbf{v}_{2}\right\}$, and (b) for what values of h is $\left\{\mathbf{v}_{1}, \mathbf{v}_{2}, \mathbf{v}_{3}\right\}$ linearly dependent? Justify each answer. $$ \mathbf{v}_{1}=\left[ \begin{array}{r}{1} \\ {-3} \\ {2}\end{array}\right], \mathbf{v}_{2}=\left[ \begin{array}{r}{-3} \\ {9} \\ {-6}\end{array}\right], \mathbf{v}_{3}=\left[ \begin{array}{r}{5} \\ {-7} \\ {h}\end{array}\right] $$
