A larger image is produced when > A smaller image is produced when < An upright image  is produced when m is positive

An upright image  is produced when m is negative

Explanation:

The mirror equation is given as follows;  For concave mirrors, f = focal length = Image distance from the mirror (-ve = Image is behind the mirror +ve = Image is in front of the mirror) = Object distance from the mirror (-ve = Object is behind the mirror +ve = Object is in front of the mirror)

m = Magnification (-ve m = Inverted image +ve m = upright image) = Image height = Object height

f = Focal length of the mirror

To produce a larger image > To produce a smaller image < To produce an upright image, m should be positive hence, will be negative or the image will appear behind the mirror

To produce an inverted image, m should be negative hence, will be positive or the image will form in front of the mirror.
