If $A=\begin {bmatrix} 1 & -2 \\ 4 & 5 \end{bmatrix}$ and $f(t)=t^2-3t+7$, then $f(A)+ \begin {bmatrix} 3 & 6 \\ 12 & -9 \end{bmatrix} = $

\[\begin {array} {1 1} (1)\;\begin {bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix} & \quad (2)\;\begin {bmatrix} 0 & 0 \\ 0 & 0 \end{bmatrix} \\ (3)\;\begin {bmatrix} 0 & 1 \\ 1 & 0 \end{bmatrix} & \quad (4)\;\begin {bmatrix} 1 & 1 \\ 0 & 0 \end{bmatrix} \end {array}\]
