Calculators TI-89 won't graph whole function?

  1. Oct 10, 2012 #1
    When I try and graph x^(2/3) in my TI-89, it only graphs the half of the graph where x>0.
    My TI-84 gives me this:
    But my TI-89 only gives me the right half. Is one of my settings wrong?

    I believe that you can get the same graph given by the TI-84 by going into the "Mode" menu and selecting "Real" as the "Complex Format" type.
