Homework Help: Graph analizing question

  1. Feb 3, 2010 #1
    the first part of the solution finds C
    by using the property that the integral on the density function equals 1

    the problem starts in the second part of the question
    i need to find the distribution function of Y
    where Y=||x|-1|
    (my problem i written bellow the photo)

    for y<0 we have no graph so the probability is 0.
    but when its from zero to 1 it touches four points
    i dont know how they got the integral from that fact?
    the same goes for when y>1
    what is the logic?
