3 area = k L^2
5 volume = k L^3
7 mass = k L^3
for the others the increase tends to be a constant times the present value (like if every woman has two kids, the next generation will be twice the present one)
dF(t) = k F(t) d t
dF/F= k dt
ln F = k t + c
F = e^(kt+c) = C e^kt
Which means EXPONENTIAL MODEL not power model
