Logistic functions such as N t 500 1 50e 0 13t are often used to model population growth Suppose a population is modeled by this function with time t measured in years Logistic population growth always has a limiting value known as the environmental carrying capacity It is the largest population that the environment can suppor Plot the graph of the population and the line that corresponds to the value of the environmental carrying capacity for this population over the first 80 years Enter expressions in terms of t to graph Separate multiple expressions with commas
