Question summary: Fie matricele A=[[-2,2],[0,-2]] şi B=[[2,1],[3,-4]]. Se consideră funcţia liniară [straight f colon straight M subscript 2 open parentheses straight real numbers close parentheses rightwards arrow straight M subscript 2 open parentheses straight real numbers close parentheses space], f(X)=a·X+b·I2, unde a=2 şi b=-2. Pentru aplicaţiile de mai jos, asociaţi matricea răspuns corectă. {f(A · B); f(A)+f(B); f(A+B); f(A) · f(B)} -> {[[2,-20],[-12,14]]; [[12,-52],[-36,60]]; [[-4,6],[6,-16]]; [[-2,6],[6,-14]]}
Right answer summary: f(A · B) -> [[2,-20],[-12,14]]; f(A)+f(B) -> [[-4,6],[6,-16]]; f(A+B) -> [[-2,6],[6,-14]]; f(A) · f(B) -> [[12,-52],[-36,60]]
