Question 2
Let $G = \{ [2, 0, 4, 0], [0, 1, 0, 1], [0, 0, -1, -1] \}$ and $\vec{v} = [1, 3, 7, 8]$. Determine whether $\vec{v} \in \text{Span}(G)$. If it is, fill in the blanks with the correct coefficients. If it is not, fill in the blanks with NA.
$\vec{v} = \text{_____} [2, 0, 4, 0] + \text{_____} [0, 1, 0, 1] + \text{_____} [0, 0, 1, 1]$
