Function: explorative model
Draw the graphic of a function
If you push the "play" button, the orange point will start to move from left to right along the Cartesian plane, i.e., increasing values for the x coordinate.
You can move the orange point up and down on the blue line.
Every time you do so, you will get the graphic of a function.
Push "restart" to begin a new graphic (CONTROL+F resets the graphic view)
