No.

(a) 3 = e^{-2k}: This means that N increases by 200% (1 to 3) with
negative k.

(b) *l*n(1/3) = -2k: This means that N decreases by a
factor 200% (1 to 3) in 2 days.

(d) *l*n(3/2) = -3k: This means that N increases by 33 1/3% (2 to 3)
in 3
days and k is negative.

(e) *l*n(1/3) = -3k: This means N decreases by 200% (1 to 3) in 3
days.
