1. It will never form an inverted image.
2. The image moves towards the focus when the object moves towards the mirror.
3. Depending on the position of the object with respect to the mirror, the image can be inverted and real.
4. The size of the image becomes larger than that of the object when the object is placed at a distance equal to half the focal length.
