2. Let c be a positive number. A differential equation of the form = ky¹+e, where k is a positive constant, is called a doomsday equation because the exponent in the expression ky¹+c is larger than the exponent 1 for natural growth. a) Determine the solution that satisfies the initial condition y(0) = yo. b) Show that there is a finite time t = T (doomsday) such that lim→T- y(t): = ∞. c) An especially prolific breed of rabbits has the growth term ky¹.01. If two such rabbits breed initially and the warren has 16 rabbits after three months, then when is doomsday?

2. Let c be a positive number. A differential equation of the form d = ky¹+e, where k is a positive
constant, is called a doomsday equation because the exponent in the expression ky¹+c is larger than
the exponent 1 for natural growth.
a) Determine the solution that satisfies the initial condition y(0) = yo.
b) Show that there is a finite time t = T (doomsday) such that lim T-y(t) = ∞.
c) An especially prolific breed of rabbits has the growth term ky1.01. If two such rabbits breed
initially and the warren has 16 rabbits after three months, then when is doomsday?
