For a camera with a lens of fixed focal length F focus on an object located at a distance x from the lens, the film must be placed at a distance y behind the lens, where F, x, and y are related by 1 1 + 1 %3D y F Suppose the camera has a 55-mm lens (F=55). A. Express y as a function of x and graph the function. B. What 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 closer to the lens?
