Problem 7. (1 point) Let a. A basis for the null space of A is { vectors, such as <1,2,3>,<4,5,6>. b. The dimension of the null space of A is A. The basis we found for the null space of A has two vectors. B. Trel(A) has a pivot in every row. C. rref(A) is the identity matrix. D. Two of the three columns in rref(A) do not have a pivot. E. Two of the three columns in rref(A) have pivots. F. rref(A) has two free variable columns. G. rref(A) has one free variable column. c. The null space of A is a subspace of d. The geometry of the null space of A is choose A = -9 -3 -12 because choose -12 9 -4 3 -16 12 }. You should be able to explain and justify your answer. Enter a coordinate vector, such as <1,2,3>, or a comma separated list of coordinate because (select all correct answers -- there may be more than one correct answer):
