Let -3 A = 12 -7 -6 9 9 -21 -4 11 a. A basis for the row space of A is { coordinate vector, such as <1,2,3>, or a comma separated list of coordinate vectors, such as <1,2,3>, <4,5,6>. b. The dimension of the row space of A is answer): A. Two of the three rows in rref(A) have pivots. B. The basis we found for the row space of A has two vectors. C. rref(A) is the identity matrix. }. You should be able to explain and justify your answer. Enter a because (select all correct answers there may be more than one correct D. Two of the three rows in rref(A) do not have a pivot. E. rref(A) has a pivot in every row. F. Two of the three columns in rref(A) are free variable columns. c. The row space of A is a subspace of d. The geometry of the row space of A is a 2-dimensional plane through the origin inside R^3 because each row of A is a vector in R^3
