3.Sketch the following, indicate roots, local extrema, inflection point, concave structure, and asymptotic lines (if applicable). (20%) f(x)=8x5 -5x4-20x3

(13) A logistic population model with relative growth rate 0.1 per year and carrying capacity 50 thousand can be expressed by the differential equation =0.1P(1 - ), with P in thousands and t in years. Given that the initial population is 9 thousand. Find the population size after 20 years. (If you memorized the formula, then you need to derive it for this problem.)
