An object is placed at distance of f/2 in front of convex lens of focal length 'f'.
If the object is at f/2 distance then it means it is between the focus and optical centre of lens
And we know, that when an object is placed between the focus and optical centre of convex lens then the image is formed behind the object and the nature of image is virtual, erect and magnified.

By lens formula,

Hence, if object is placed at f/2 distance then the image is formed behind the object at focal length. Negative sign indicates that image if forned at same side as that of object.
