You are given the graph of `f(x)`, and your task is to show what `f'(x)` looks like.
Explore
- The graph of `f(x)` is shown in black. Drag the blue points up and down so
that together they follow the shape of the graph of `f'(x)`.
- When you think you have a good representation of `f'(x)`, click the "Show results!"
button below the applet. This reveals the true graph of `f'(x)`, drawn in red.
- You can continue to move points and see how the accuracy changes.
