The lens shown has radii 12.3cm and 24.6cm and is made of a material with index of refraction 1.58. Use the shape of the lens to assign the given radii and their signs (hint: which side looks more curved?). If an object is placed 14.2cm from the lens, what will be the position of the image? Give a positive or negative value for the image position, using the usual sign conventions for lenses
