Assume the cubic function f (x) = x 3 - 15x 2 - 600
(a) Create a table for the values of x from 6 to 20 and their corresponding values for f (x).
(b) Graph the f (x) function.
(c) Use the information from parts (a) and (b) and find the first and second degree approximations to the cubic function using the Taylor expansion series.
