The population of Who-ville from 2000 through 2007 can be modeled by P(t) = 1100 / 1 + 2.985 ^ (-0.4t)
where t represents the year, with t equals 0 corresponding 2000

1. use the model to find the population in the year 2003. round to the nearest person

2. use the model to find the initial population of the year 2000. round to the nearest person

3. this model is a logistic function graph the function and determine the maximum value of the population. round to the nearest person
