Question
f(x) = 36x + 3x2 - 2x3
a) Find the intervals of increase or decrease
b) Find the local maximim and minimum values
c) Find the intervals of concavity and the inflection points
d) Use the information from parts a-c to sketch the graph
Note: I tried working out this problem, but get stuck at part a. I learned to use a table to find the intervals of increase or decrease but cannot understand why I keep getting the opposite of what the answer should be. Please explain your steps so I can learn how you get increasing or decreasing for f(x) in the table. Thank you.
*please use handwriting not type, I understand it better that way*
