A matrix, A, is diagonalizable if there exists an invertible matrix $S$ such that $S^{-1}AS$ is a diagonal matrix, and in that case, we say that $S$ diagonalizes $A$. Suppose $A = \begin{bmatrix} 4 & 1 \\ -2 & 1 \end{bmatrix}$. Which matrix $S$ diagonalizes $A$, if any? $S = \begin{bmatrix} -1 & 1 \\ -1 & 2 \end{bmatrix}$ $S = \begin{bmatrix} -1 & -1 \\ 1 & 2 \end{bmatrix}$ A is not diagonalizable $S = \begin{bmatrix} 3 & 0 \\ 0 & 2 \end{bmatrix}$
