For fixed positive integers m and n, the set upper m subscript m times n of all mtimesn matrices is a vector space, under the usual operations of addition of matrices and multiplication by real scalars. let f be a fixed 3times2 matrix, and let h be the set of all matrices a in upper m subscript 2 times 4 with the property that faequals0 (the zero matrix in upper m subscript 3 times 4). determine if h is a subspace of upper m subscript 2 times 4.
