Let A = c. The image of A is a subspace of choose -3 -1 12 14] -3 0 0 a. A basis for the image of A is }. To submit your answer, you may enter a coordinate vector, such as , or a comma separated list of coordinate vectors, such as ,. d. The geometry or shape of the image of A is choose 0 0 b. The dimension of the image of A is than one correct answer): A. Two of the three columns in rref(A) do not have a leading one (or pivot). OB. Two of the three columns in rref(A) have leading ones (or pivots). OC. Two of the three columns in rref(A) are free variable columns. D. rref(A) has a leading one (or pivot) in every row. OE. The basis we found for the image of A has two vectors. F. rref(A) is the identity matrix. because (select all correct answers -- there may be more (enter "R^n" with “n” being an actual number) because
