Consider A = = with a corresponding A = = 3 4 1 -4-3 3 4 3 32 22 -2 -4 • State a basis for the column space of A. • Choose one of the columns from A not selected as part of the basis and show how it is a linear combination of your basis. 5. Using the same matrix A as in the previous problem: • State a basis for the null space (kernel) of A. • Give an example of a nonzero vector in the null space that is not one of your basis vectors.
