-2 4 -21 A = -4 -1 -2 -2 1 A basis for the image of A is { }. To submit your answer, you may enter a coordinate vector, such as <1,2,3>, or a comma separated list of coordinate vectors, such as <1,2,3>,<4,5,6>. The dimension of the image of A is because (select all correct answers -- there may be more than one correct answer): A. The basis we found for the image of A has two vectors. B. Two of the three columns in rref(A) do not have a leading one (or pivot). C. Two of the three columns in rref(A) are free variable columns. D. Two of the three columns in rref(A) have leading ones (or pivots). E. rref(A) is the identity matrix. F. rref(A) has a leading one (or pivot) in every row. The image of A is a subspace of (enter "R^n" with "n" being an actual number) because choose The geometry or shape of the image of A is choose
