Point

A(0,1\,\text{cm})

and point

B(12\,\text{cm},5\,\text{cm})

are the coordinates of an object and its image, respectively. The

x

-axis is the principal axis of the mirror. This object-image pair is (1) due to a convex mirror of focal length

2.5\,\text{cm}

(2) due to a concave mirror having its pole at

(2\,\text{cm},0)

(3) due to a concave mirror having its pole at

(-2\,\text{cm},0)

(4) Data are insufficient
