2. Graph f(x) = 3x(x + 2) / ((x + 4)(x - 2)). Note its derivatives are f'(x) = -48(x + 1) / ((x + 4)^2(x - 2)^2) and f''(x) = 144(x^2 + 2x + 4) / ((x + 4)^3(x - 2)^3). Label important points and asymptotes on the graph. You must find the following, with justification. Write "None" as needed. Asymptotes: Intercepts: Local maxima (as points): Increasing: Local minima (as points): Concave up: Inflection points:

You volunteered at Habitat for Dogmanity where you build houses for dogs. You recently built a strange house for Puddles and now she's asking you to approximate the integral of the roof using the Trapezoidal Rule and n = 5. (Probably for her dog taxes). The roof looks suspiciously like y = tan(cos x) over the interval [-?, ?]. She said she wants her answer rounded to 4 decimal places.

Parker and Glenn, the two sons of railroad tycoon Scott Piggy, are having a contest to see who can make a longer set of tracks on the interval ( [-1,1] ). Parker built his track along ( x^{2 / 3}+y^{2 / 3}=1 ) while Glenn followed the route of ( y=-|2 x|+2 ). Which of the two brothers has the longest track and will win his father's pride? (To get full credit, use calculus to find the lengths!)
