## Homework Statement

Identify the inflection points, local min/max and intervals the graph is rising, falling, conc up/down analytically, support graphically.

y=-x^3-3x^2-4x-2

## Homework Equations

## The Attempt at a Solution

F'(y)=-3x^2-6x-4

x=-1+/-.5775i

F"(y)=-6x-6

x=-1

I've done this before and I can do it analytically for roots that aren't imaginary...I also need help with the sign graph for the roots...
