Can an object be halfway between focal point and diverging mirror?

A physics question from Principles of Physics by Mazur in the chapter on Optics is asking me to "repeat Problem 92 for a diverging mirror", and one of the questions in Problem 92 (which is about a converging mirror) is to find the image distance of an object halfway between the focal point and the mirror.

I do not believe this is possible, since the focal point of a diverging mirror is behind the mirror, and so an object halfway between the focal point and the mirror is also behind the mirror.

I think I figured it out. Table 33.2 in the text has a footnote in the "o < 0" case: "Encountered only with lens or mirror combinations". If any mirror is in combination with other mirrors and lenses, it may be the case that the object is behind the mirror.
