Estimate the value of each derivate.

Hello!

i got problem with solving this, ik how to graph its derivate the i mean 1.-1 Will be roots... I see it Will first be positive to -1 then negative to 0 then positive to 1 and countinue possitive. I got problem calculate those, i shall get the slope but i do wrong when ik just how the graph looks like.

If you **just must** post an image, why don't you at least make sure it is clear (well lighted) and therefore readable?
