Fthe number of bacteria in a colony triples every 60 minutes and the population is currently 2,000 bacteria, what will the population be in 240 minutes and is the growth modeled by a linear function or a exponential function?

The number of bacteria present in the colony after t hours given that it triples every 60 minutes, the equation that would best describe it is,
                          At = (A0)(3)^(t/60)
Substituting the known values,
                          At = (2,000 bacteria) x (3^240/60)
The answer would be 162,000 bacteria after 30 seconds.

The answer will be that the bacteria population is 162000 after 240 hours, and it modeled linear function. Hope it help!
