for question 2 part d-e

1. For each first order ODE, determine if it is separable, linear, exact or exact after using an
integrating factor, homogeneous, and/or Bernoulli. Multiple labels may apply. Justify all
conclusions. You do not need to solve.
(a) - ²y = 0
(b) x² + 2xy = 0
(c) y² - xy = 0
(d) ry³ + ¹y+d=0
(e) = (x+y + 2)²
