Answer:

By obtaining the Real image of a distant object at its focus, the focal length of the concave mirror can be estimated as shown in the diagram. The focal length of the convex mirror is positive, whereas that of the concave mirror is negative. The same can also be proved by using the mirror formula: (1/f = 1/v +1/u).
