Current Attempt in Progress

More lenses. Object $O$ stands on the central axis of a thin symmetric lens. For this situation $($see the table below, all distances are in centimeters$),$ find $($a$)$ the lens type, converging or diverging, $($b$)$ the focal distance $f,($c$)$ the image distance $i.$ It also refers to whether $($d$)$ the image is real or virtual, $($e$)$ inverted or noninverted from $O,$ and $(f)$ on the same side of the lens as $O$ or on the opposite side.
