Final answer:
In the bacteria example, the rate at which bacteria multiply is exponential, with the population doubling after each generation.
Step-by-step explanation:
In the bacteria example, the rate at which bacteria are multiplying is exponential. Each bacteria divides and produces two offspring, resulting in a doubling of the population size. After each generation, the number of organisms added doubles. In the given example, after 1 hour, the population increases from 1000 to 2000, after 2 hours it increases to 4000, and after 3 hours it increases to 8000. In the bacteria example, the rate at which bacteria are multiplying is exponential. Each bacteria divides and produces two offspring, resulting in a doubling of the population size. This exponential growth continues until the population reaches more than 16 billion after 24 cycles.
