The number of bacteria colonies on a petri dish can be determined by the function below.

n(t) = 2(3)t

answer choice:
-When the observation began, there were 2 bacteria colonies, and the number of bacteria colonies increased by a factor of 3 for every time interval, t.
-When the observation began, there were 3 bacteria colonies, and the number of bacteria colonies increased by a factor of 2 for every time interval, t.
-The final number of bacterial colonies is found by multiplying the 2 original colonies by 3
-After 3 minutes, there are 2 bacteria colonies.

Which statement represents the meaning of the a and b values from the function in terms of the problem situation?
