A species of fish was added to a lake. The population size P (t) of this species can be modeled by the following exponential function, where t is the number of years from the time the species was added to the lake.P (t) =1000/(1+9e^0.42t) Find the initial population size of the species and the population size after 9 years. Round your answer to the nearest whole number as necessary. Initial population size is : Population size after 9 years is:
