Give a geometric description for the rowspace, column space and nullspace of A. c. Use your information from a and b to confirm Rank-Nullity d. Show that the vectors of the rowspace and the vectors of the nullspace form a basis for a space of R". state what n is. -1 1 2 1 3 3. Suppose that A =1 2 0 2 1 l-1 0 0 1 -1l a.
