 Now, simply type the x-coordinate that you desire on the calculator pad.  Let's hit the key for "5".
 x = 5 will appear on the screen.
 Now, hit
  . The "spider" will jump to the new point, and
 the coordinates will appear in the lower right corner of the graph screen.
 If you choose a value out of the current viewing window, the graph will adjust to include your new point. |  |
