​ Is the given set a basis for R 3
? A. No, because these three vectors form the columns of a 3×3 matrix that is not invertible. By the invertible matrix theorem, the following statements are equivalent: A is an invertible matrix, the columns of A form a linearly independent set, and the columns of A span R n. . B. Yes, because these three vectors form the columns of a 3×3 matrix that is not invertible. By the invertible matrix theorem, the following statements are equivalent: A is a singular matrix, the columns of A form a linearly independent set, and the columns of A span R n
. C. Yes, because these three vectors form the columns of an invertible 3×3 matrix. By the invertible matrix theorem, the following statements are equivalent: A is an invertible matrix, the columns of A form a linearly independent set, and the columns of A span R n
. D. No, because these three vectors form the columns of an invertible 3×3 matrix. By the invertible matrix theorem, the following statements are equivalent: A is a singular matrix, the columns of A form a linearly independent set, and the columns of A span R n. .
