Answer 1

In a concave mirror that type of the image formed depends on the position of the object.

Depending on the position of the object, the image can be both real or virtual, erect or inverted and magnified or diminished.

For example, if the pencil is held beyond the centre of curvature of the concave mirror, the image of the pencil will be diminished in size and an inverted image.
