i hope if magnification is negative then real image will form so concave mirror. and if magnification is positive then virtual image will form so convex mirror.

magnification m is positive => convex mirror (image is virtual and diminished)
magnification m is negative => concave mirror because image is real (except in the case of object between F and P image is virtual and enlarged)
magnification m = +1 => plane mirror as image is virtual.
