A concave is not a shape. It is a characteristic of one. It is like asking how many parallel lines a small has.
A concave mirror bulges away from the incident light. The image of an object depends on where exactly the object is placed - relative the to focal length of the mirror. See the attached link for more details.

Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
The sheep's eye is concave, the surface of the shape of the lens are circular.
If it is symmetric then it looks like an arrowhead.
