A gray squirrel population was introduced in a certain region 27 years ago. Biologists observe that the population doubles every nine years, and now the population is 440. (a) What was the initial squirrel population? (b) What is the expected squirrel population, P, r years after introduction? P(r) = squirrels (c) Estimate the expected squirrel population 10 years from now. (Round your answer to the nearest integer.) Starting with the graph of y = e", write an equation of the graph that results from the following changes. (a) shifting 9 units downward y: H (b) shifting 7 units to the right y: H (c) reecting about the X-axis y: H (d) reecting about the yaxis y: H (e) reecting about the xaxis and then about the yaxis y: H
