a) (4 pts) Find the basis for the null space of the matrix below 1 2 0 1 A = 2 4 1 4 3 6 3 9 b) (4 pts) Use the Gram-Schmidt process to create an orthonormal basis from the basis found in part a). . For full (or any) credit, show the main steps of your work and your reasoning. You need to explain how you know that the vectors found in part a) form a basis for null(A). You may use Matlab to check your answer for this question, but the work you show must be done by hand. a) (4 pts) Find the basis for the null space of the matrix below 1 2 0 1 A = 2 4 1 4 3 6 3 9 b) (4 pts) Use the Gram-Schmidt process to create an orthonormal basis from the basis found in part a). .
