Now I'm curious [but not smart  board.] You can move the graph. Does the
function that describes it change accordingly as it is moved? I can see going
from a changed function to the graph, but can not see, or know of any software
that will, deriving the function from a repositioning of the graph ...well not
immediately at least; the relation can be found from given or determined points
on the graph, at least approximately in general.
