Question

NEED HELP WITH PART E AND D, PLEASE.

1. Let f(x)= 3x² - 4x³ - 12x².
(a) Find all critical numbers for the function f.
(b) Determine all those intervals on which the graph of f is increasing and all those on
which it is decreasing by analyzing the sign of the derivative function.
(c) Find and classify all of the relative extreme values/points by applying the First
Derivative Test.
(d) Sketch a graph of y = f (x) based on your findings in parts (a) - (c).
