Tractrix A person walking along a dock drags a boat by a10-meter rope. The boat travels along a path known as a tractrix.The equation of this path is y = 10 ln10 + 100 − x2x  − 100 − x2.(a) Use a graphing utility to graph the function.(b) What are the slopes of this path when x = 5 and x = 9?(c) What does the slope of the path approach as x approaches10 from the left?
