WebSo a basis for the null space of A is the vector (1/2, 1/2, 1). Since the nullity is the dimension of the null space, the nullity of A is 1. c) To find a basis for the range of A, we can find the pivot columns of the reduced row echelon form of A from part a). The pivot columns are the first and third columns of the matrix B. looking for driving job code 10 with pdp
