m = -2 
negative indicates that the image formed is real and inverted
And value 2 indicates that the size of image formed is twice the size of the object. 
In case of concave mirror the object formed is real, inverted and magnified only when the object is placed beyond the centre of curvature of mirror. 
Thus, object must be placed beyond centre of curvature (C) of concave mirror so as to obtain the magnification of -2.
