Analyze the graph of the given function f as follows:(a) Determine the end behavior: find the power function that the graph of f resembles for large values of |x|.(b) Find the x- and y-intercepts of the graph.(c) Determine whether the graph crosses or touches the x-axis at each x-intercept.(d) Graph f using a graphing utility.(e) Use the graph to determine the local maxima and local minima, if any exist. Round turning points to two decimal places.(f) Use the information obtained in (a) - (e) to draw a complete graph of f by hand. Label all intercepts and turning points.(g) Find the domain of f. Use the graph to find the range of f.(h) Use the graph to determine where f is increasing and where f is decreasing.f(x) = (x - 3)(x - 1)(x + 2)

Solve the problem.If a population is changed by either immigration or emigration, a model for the population is 
where y is the population at time t and f(t) is some function of t that describes the net effect of the emigration/immigration. Assume that k = 0.02 and y(0) = 10,000. Solve this differential equation for y, given that 
A. y = 650t + 32,500 - 22,500e-0.02t B. y = -650t - 32,500 - 22,500e0.02t C. y = 650t + 32,500 - 22,500e0.02t D. y = -650t + 32,500 - 22,500e-0.02t
