The velocity function is http://math.webwork.rochester.edu:80...111267d211.png for a particle moving along a line. Find the displacement and the distance traveled by the particle during the time interval [0,6].

displacement = distance traveled =

OK so I found the displacement which is -12, but I can't find the distance. I know I have to find when it changes directions and I found it did that at x=3. Can someone help? Thanks
