Bat Population The bat population in a certain Midwestern county was 350,000 in 2012, and the observed doubling time for the population is 25 years. (a) Find an exponential model n(t) = n, 201a for the popula- tion i years after 2012. (b) Find an exponential model n(t) = nge" for the popula- tion i years after 2012. (c) Sketch a graph of the population at time 1. (d) Estimate how long it takes the population to reach 2 million.
