1. All matrices in the following statements are n x n matrices. Mark each statement TRUE or FALSE. If FALSE, justify. (a) A is diagonalizable if A = PDP^{-1} for some matrix D and some invertible matrix P. (b) A is diagonalizable if and only if A has n eigenvalues, counting with multiplicities. (c) If A is diagonalizable, then A is invertible. (d) If A is diagonalizable, then A has n distinct eigenvalues.
