A population of rabbits in a forest follows a logistical growth model. If the carrying capacity is 500 and the initial population is 50, describe the population growth over time.

• The population will grow exponentially without limits.

• The population will grow rapidly at first, then slow down as it approaches 500.

• The population will decrease over time.

• The population will remain constant at 50.
