1) Drag the White dots up and down to make the line segments tangent.[br]2) Then select the "Check your work" button.[br]3) Answer the question below[br][br][br][br]
How is the white graph related to the blue graph?
The white graph is the derivative of the blue graph. Notice how each point on the white graph is the value of the slope of the tangent on the blue graph.
4) Now move the green dots to change the shape of the graph.[br]5) Repeat steps 1 and 2. [br][br][br][br]
If you would like to try this exercise multiple times, simply use the delete icon [icon]/images/ggb/toolbar/mode_delete.png[/icon] to erase any previous sketches you made. Then, reposition any one (or more) of the four [b][color=#38761d]green points [/color][/b]to get an entirely different graph. [br][br][i][b][color=#38761d]Just be sure not to move any green points in the middle of an exercise[/color][/b], at it will change the graph of the entire function. [br][br][/i][b]Note: [/b][br]If you do move any of the [b][color=#38761d]light green points[/color][/b] and the function graph disappears, simply refresh the page in your browser.
