What is a solution to a differential equation?
2. Check which functions below satisfy the following second-order differential
equaiton:
y (t) = 25y(t)

(b) y(t) = 2e5t
(c) y(t) = 5e-5t
(d) y(t) = e5t
+ e-5t
(e) y(t) = 3e5t
- 2e-5t
3. (Long-term Behavior) Let y(t) (read "y of t") be the snowy plover pop-
