Question

Hi please help and clearly state the end answer. 

For each problem below, you're given a function and its first and second derivatives.
a. Find the domain and zeroes of f (x).
b. Find out what f'(x) and f"(x) tell you about the shape of f (x).
С.
Use this information to help you draw a good sketch of the function that shows all x-intercepts,
max/min values, and inflection points.
(In the future, you will be asked to do this given the function only - so be sure you can find these derivatives
and get them into a useful form to find their zeroes.)
1. f(x) — х4 — 2х3
f'(x) = 4x³ – 6x?
f"(x) = 12x2 – 12x
