Practice Problem on Lenses in Combination
Two lenses are placed on the x-axis. The first lens is a converging lens with focal length 5 cm placed at x = -9 cm. The second lens is a diverging lens with focal length 9 cm placed at x = 7 cm. If an object is placed at x = -14 cm, what is the position of the image, image type (virtual or real), and magnification of the image?

ANSWER = (x = -2.00 cm, virtual, m = -nan)
