Is it x-1 or x+1. If you could answer the whole problem that would be appreciated, but it is a calculus question, but I am stuck on one of the algebra parts. Thanks.Answer by stanbon(57966)   (Show Source): You can put this solution on YOUR website!For x>=1, [sqrt(x-1)]^2 = x-1 -------- For all x, sqrt[(x-1)^2]= |x-1| --------- Cheers, Stan H.
