Question
(a) For a diverging lens (f =–17.0 cm), find the image distance for an object that is 18.0cm from the lens. (b) Determine the magnificationof the lens. I got the correct answer of -8.77 cm for part A, but for partB, I assume I use the equation M = -di/do, and used -8.77 as di and18 as do, but I am getting the wrong answer (-4.87) ???

Distance of the object do = 18 cm
Distance of the image di = -8.77 cm
Magnification m = di / do
= -0.487
