(A) The image is formed 2.5 cm to the right of the mirror and it has a magnification of −1/2.
(B) The image is formed 5.0 cm to the right of the mirror and it has a magnification of −1.
(C) The image is formed 2.5 cm to the left of the mirror and it has a magnification of 1.
(D) The image is formed 5.0 cm to the left of the mirror and it has a magnification of −1.
(E) The image is formed 1.25 cm to the left of the mirror and it has a magnification of −1/4.

解題流程
1.concave mirror(凹面鏡) =凸透鏡f為+
2.R=2f f=+2.5cm 
3.1/p+1/q=1/f 得q=5cm
4.放大率=-q/p=-1
