Solve the initial value problem f'(x) = x2 - 2x with f (1) = 1/3 Suppose the function f(x) is continuous and always positive. If G is an antiderivative of f, then we know pints that G (check and justify your answer): a) is always positive b) is always increasing c) is sometimes positive and sometimes negative d) there is not enough information to conclude any of the above
