A function and its derivative

Use checkboxes to select a function to display on the upper set of axes, labeled f(x). The point S on the lower axes (labeled f'(x)) represents the local slope (derivative) of f(x) at the point A. Drag point A to map out the shape of the function f'(x). Note that the relationship between the vertical scales of the two graphs is arbitrary.
