Confused on how the absolute value changes the method of deriving

  1. Apr 30, 2013 #1
    1. The problem statement, all variables and given/known data

    Find derivative of abs (2x^3 + 8x^2 + 5x +1).


    2. Relevant equations



    3. The attempt at a solution

    A little confused on how the absolute value changes the method of deriving that equation. When I derive it normally, I get (6x^2+16x+5).

    It might help to do simpler examples that you can graph - compare the derivative of abs(x) to the derivative of x or x2-1 vs abs(x2-1)
