WebThen B is the identity matrix, so ker(B) = f0g. But every vector has image zero under AB, so ker(AB) = R2. Certainly ker(B) does not contain ker(AB) in this case. (b)Suppose y is in the image of AB. Then y = ABx for some x 2Rm. That is, y = ABx = A(Bx); so y is the image of Bx under multiplication by A, and is thus in the image of A.
