enter image description here

In a situation like this, I understood that the focal length is half of that of the original lens. However, I don't know whether its image is inverted or not. In this situation, will the image be inverted?

The image will be inverted. You can think this combination as concave mirror. The beam reflected from the mirror will be converging spherical wave same as concave mirror (ideally).
