In the following matrix, how many columns are linear combinations of the columns preceding it? 0 3 2 3 A = 3 3 2 0 2 1 2 1 3 3 2 0 Consider the matrix O o -2 -1 Co Co A = 1 -2 0 O L 0 Suppose T : R4 - R* is the linear transformation defined by the formula T(ac) = Axc. Determine if T is injective but not surjective, surjective but not injective, neither injective nor surjective, or bijective (meaning injective and surjective). O T is injective but not surjective. O T is surjective but not injective. O T is neither injective nor surjective. O T is bijective (i.e., it is injective and surjective)
