(1 point) Please answer the following questions about the function 3x2 3:2 4. f(x) = instructions: - If you are asked for a function, enter a function. - If you are asked to find x or yvalues, enter either a number or a list of numbers separated by commas. If there are no solutions, enter None. - If you are asked to find an interval or union of intervals, use interval'notation. Enter {} if an interval is empty. - If you are asked to find a limit, enter either a number, | for 00, | for 00, or DNE if the limit does not exist. (a) Calculate the first derivative off. Find the critical numbers of f, where it is increasing and decreasing, and its local extrema. *2 f'(x) = )? Critical numbers x = Union of the intervals where f (x) is increasing Union of the intervals where f (x) is decreasing Local maxima x = 0 Local minima x = D
