Find the nature of image when an object is placed at 2f from the pole of a convex mirror of focal length f

An object is placed at a distance x from the principal focus of a spherical mirror of focal length f. The magnification of the image will be

An objected is placed at the principle focus of a convex mirror. The image will be at

an object is placed at the principle focus of a concave lens of focal length f. where will its image be formed?

If the object distance and image distance from the focus of a spherical mirror of focal length f be x and y respectively, then
