A ray diagram is shown. A flower is an object in front of a convex mirror. A ray parallel to the principal axis reflects away from the focal point. The second ray goes to the mirror toward the focal point and reflects parallel to the principal axis. The reflected rays are continued onto the other side of the mirror as dashed lines. At the intersection of the two dashed lines is a small upright image of the object in front of the focal point.

Which describes the image?
It is virtual and in front of the mirror.
It is virtual and behind the mirror.
It is real and in front of the mirror.
It is real and behind the mirror.
