Suppose a 6x8 matrix A has three pivot columns. What is nullity A? Is Col A = R3? Why or why not? .. nullity A = |(Simplify your answer.) Is Col A = R? Why or why not? A. Yes, because the number of pivot positions in A is 3. O B. No, because Col A is a subspace of R°. C. Yes, because rank A = 3. O D. No, because Col A is a subspace of R°.
