Math Help - Estimate the value of each derivate.

1. 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?
