EXPLORING THE SQUARING FUNCTION WITH GEOGEBRA
  • The point labeled MoveMe
    is a typical point
    of the form $\,(x,x^2)\,$.
  • To begin, click anywhere in the GeoGebra window to make it active.
  • Then, click on MoveMe to make this point active—it will appear highlighted when it is active.
  • Use the right and left arrow keys on your keyboard to move the point along the curve.
  • At any time, you can press your browser ‘refresh’ button to restore the page to its initial configuration.
Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and activated. (click here to install Java now)
