Answer:The mirror is a Concave Mirror. Thr focal length is -15 cm.
Explanation:A Convex mirror never gives a real image. Thus, the mirror is a Concave mirror.
If you have a doubt with the formula I used to calculate f, you can calculate f also by mirror formula. Warning:Do not use this formula in Boards!
