With the sliders you can adjust the parameters of the function (for

*not equal to 0 it is a cubic function). What do the points A and B represent? Make the first derivative f'(x) visible by clicking on the bubble next to it in the Algebra view***a**## Questions

What link is there between the roots of the first derivative and the stationary points (extrema) of f(x)?
What is the point G? Is there a connection between point G and ?
What about the second derivative of f? What does it tell you?
