Question 2 Construct a basis of \(\mathbb{R}^4\) that contains both \(\begin{bmatrix} 7 \\ -2 \\ 3 \\ 7 \end{bmatrix}\) and \(\begin{bmatrix} 3 \\ -1 \\ 2 \\ 1 \end{bmatrix}\). Make sure you prove that your choice is in fact a basis.

4. Tell whether or not the following sets form a basis of the stated vector space. Show your reasoning. a. Is S = {(1, 0, 1), (0, -1, 0), (2, -1, 2)} a basis for R^3? b. Is S = {(1, 0, -2, 3), (0, 1, 0, 1), (0, 0, 1, -2)} a basis for R^4?
