If the columns of A are linearly dependent - correct answer Then the matrix is not invertible and an eigenvalue is 0 Note that A−1 exists. In order for λ−1 to be an eigenvalue of A−1, there must exist a nonzero x such that Upper A Superscript negative 1 Baseline Bold x equals lambda Superscript negative 1 Baseline Bold x . A−1x=λ−1x. Suppose a nonzero x satisfies Ax=λx. What is the first operation that should be performed on Ax=λx so tha...
