    N_t=N_0(2)^{\frac{t}{d}}

    where

    N_0 = initial number of bacteria

    N_t = number of bacteria after time t

    d = doubling time = 30 min = 0.5 hour

    t = total time

    Now solve and finish.

    I got f(x)=2(0.5)^(x/0.5) + 10 as the rule but that's wrong.

    Edit: Post above helped.
