Graph of a Function and Derivative

Enter a function and move the point P along the curve. Note the slope of the tangent to your function at the point P and its connection to the point S on the graph of the derivative. Pay attention to important points on the graph of f(x), such as where f(x) has zero slope or where it is steepest, and the connection to the graph of f'(x).

You can also adjust the axes by holding the shift button and left-click on the axis you want to change.
