What do you notice about this graph? Can you describe this jump rope scene? You can use the rules for coordinate transformations to rewrite the coordinates for points B and C in terms of the coordinates for point A, which are (x(A),y(A)). Select the box to turn on point B or C, and then drag point A along the function and watch as point B or C traces out a new curve. Can you write a coordinate rule for a person that jumps faster? For a person that jumps higher?

Create graphs for several different jump rope scences. Remember to turn on points B and C by checking the box, and to drag point A along the graph to enable the creation of the graphs for points B and C. Share these with a partner or the class to see if they can explain what is happening in the new jumprope graph.
