Find the absolute minimum and maximum of f (as) = 9:4 29:2 on the interval [0, 3]. Find the absolute minimum and maximum of f (x) = x4 2x2 on the interval [-3, 0]. Use the rst and / or second derivative tests to nd and classify all relative extrema: f(x) = a:3 + 6x2 5 A car is traveling east toward a particular city at 50 mph while a second car is traveling south away from the city at 60 mph. At time t = 0 the rst car is 30 miles west of the city and the second car is 40 miles south of the city. At what rate is the distance between the two cars changing at this time
