Calculate what is the magnification of the image

Reference no: EM13694221

Question: A diverging lens have a focal length of -10 cm. A 3-cm object is placed 25 cm to the right of the lens.

Part A- What is the magnification of the image (recall the meaning of the sign here)?

I know the answer but I don't really know how so any help is greatly appreciated.
