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.
