Dear student

The answer is 1/(m+1)

The magnification will be M=1/(x+1). Or in words: the magnification is the inverse of the distance of the object to its focal point (for a divergent lens in virtual space) in units of focal lengths. If x is the distance to the surface, you have to add another one focal length to get the distance to the object-related focal point (subtract one for convergent lenses and x usually being an absolute value). Then the inverse of that x+1 is the magnification.
