Answer:
To answer this problem , we must have knowledge of all the possible location of Object where it is to be placed and Image formed corresponds to these possible location...
Concave mirror forms Erect image only in one case when object is placed between the Pole and Principal axis...
Since focal length of a concave mirror is 12cm so the range will be 0 to 12cm...This mean if we place an object in between this range we always get erect image
