well youre right! Weve gotta find the second derivative. Lettss do it>

[tex]f'(x)=3x^2+6x+1[tex], and

good good good. so then the inflection point

good good Now plugging back in the original formula gives us (-1,2).

good good Concavity

Using a little noodle power, you can do the rest..........

- x = a is a locally a minimum if f"(a) > 0,
- x = a is a locally a maximum if f"(a) < 0; and

You can DO IT!!!!!!!!
