In Exercises 1-2, classify the matrix as upper triangular, lower triangular, or diagonal, and decide by inspection whether the ma- trix is invertible. [Note: Recall that a diagonal matrix is both up- per and lower triangular, so there may be more than one answer in some parts.] 1. 1 0 0 3 -2 7 0 00 2 0 (d) 0 0 3 95 1 0 0 8
