Given A=[ 2 1 2 1 2 1 2 1 ] Select all true statements about the matrix A. Note: there may be more than one true statement. Only select true statements. You will get points for selecting true statements and points taken off for selecting false ones. A. A =A 1 B. A A=I 2 C. Ax,y=x,A y for all x,yC 2 D. Ax,Ay=Ay,Ax for all x,yC 2 E. x,Ay=A x,y for all x,yC 2 F. A is invertible G. A =A H. A=A 1 I. Ax,Ay=x,y for all x,yC 2 J. Ax,y=x,Ay for all x,yC 2 K. A A =I 2
