Homework Help: Find the Derivative of the given Function

  1. Oct 20, 2012 #1
    1.Sketch the Derivatie of the given Function

    2. Help me find the derivative of the function

    3. I said that the derivative will begin at the origin, then slope down vertically, then continute shortly horizontally, then go back up the "X" axis and continue horizonally.

    welcome to pf!

    hi apcalckid76! welcome to pf! :smile:

    try this part …

    what does the graph of the derivative of just the slopey part in the middle look like?​

    yes, that's right :smile:

    the three parts of the original graph are straight,

    so that means their derivatives (= the slopes) are constant,

    so the graph of the derivative is three horizontal lines, at levels 0 minus-something and 0 again :wink:
