4. (30 points) Let A=⎣⎡214−102702331⎦⎤. Then the row echelon form (REF) for A is ⎣⎡100001001110⎦⎤. (a) Find a basis for the nullspace of A and find the dimension of this nullspace, i.e., dim(Nullspace(A)). (b) Find a basis for the column space of A and find the dimension of the column space, i.e., rank(A) (c) What is the dimension of the row space?
