Anew species of fish is released into a lake, and the fish multiply quickly. the growth of their population is modeled by the exponential function p(t) = 7bt, where t is the time in weeks after the release and b is a positive unknown base. after observing the population growth over a few weeks, the exponential function p(t) = 7(2)t is used to model the growth. interpret the significance of 2 in the function as it applies to the situation.

a) the population is doubling each week

b) the population is doubling each month

c) the population is counted every 2 weeks

d) the population is increasing by 2 fish each week
