y = x + square root (absolute value (x)) what are the first and second derivatives? and the extrema, concavity, any asymptotes, continuity? I dont even know where to begin

I dont even know where to begin The absolute value causes us some problems. To overcome this you should probably analyse the problem for the three seperate cases of x>0, x<0 and x=0. Case 1; For x>0 Case 2; For x<0 Using these equations you should be able to answer some of the questions above.
