Chapter 18.1, Problem 5E Step-by-step solution Step 1 of 3 5. (a) The dominant root being -7/2, the time path will eventually be characterized by explosive oscillation. Step 2 of 3 (b) The complex roots imply stepped Since > 1, the fluctuation is explosive. Step 3 of 3 (c) The repeated roots lie between 0 and 1; the time path is thus nonoscillatory and
