This applet illustrates the relationship between the utility maximization decision and the resulting demand curve.  The top graph displays the utility function described in the previous page.  The bottom graph displays the resulting demand curve in px-x space.  The vertical axis is px  and the horizonal axis is x.  As you manipulate the slider, px changes, resulting in a new choice of x.
