With the two sliders in the bottom you can change the slope of the functions. You can change the distance of the blue and the red function on the x-Axis by moving the big red button. It is also possible to move the car and the bicycle by moving the little blue and red button along the function.
What is the difference to the last worksheet? What could be a reason for this? What does the distance of the red and the blue function on the x-Axis now stand for? What happens, if the two functions now intersect? Can it now also be possible, that they don't intersect ever?
