Answer 2

Upwards

• Measurements must be made from the pole for all distances.
• Distances measured in the direction of the light's incidence are to be considered positive, while those measured in the opposite direction are to be considered negative.
• When measured from the axis, object and image height are positive when measured upward and negative when measured below.
• f and R are negative for a concave mirror and positive for a convex mirror.
• When the object is kept in an upward position, it results in positive value.
• This is because when we take anything upwards, it leads to positive value while below the axis results in negative value.

Hence, the height of object and image are positive if measured upward from the axis.
