Answer:
Magnification = 1/n.
According to mirror formula, object distance = f(n-1).
In terms of the radius of curvature, we can write Object Distance = R/2 (n-1).
Image distance = (R/2n)(n-1).
Convex mirrors produce images that are virtual, diminished and erect.
Therefore image distance is negative.
The focal length of the mirror is also negative by convention.
