For a camera with a lens of fixed focal length F to focus on an object located a distance x from the lens, the film must be placed a distance y behind the lens, where F, x, and y are related by (1)/(x) (1)/(y)=(1)/(F) (See the figure.) Suppose the camera has a 55-mm lens (F=55) . (a) Express y as a function of x and graph the function. (b) Express happens to the focusing distance y as the object moves far away from the lens? (c) What happens to the focusing distance y as the object moves close t
