Suppose f(a) is some function, and you determine the derivative is f' (x) = - 4(x + 1)(x - 2). Find the intervals on which the function is increasing and decreasing. Write the intervals using inequalities not including the endpoints. Intervals where f (x) is increasing: Intervals where f( ) is decreasing
