The images are only illustrating semicontinuity at a point. Previous phrasing implied the function was upper/lower semicontinuous in its entire domain. undo Tag: Visual edit

I think the slight redundancy is good because it presents the theorem informally and then rigorously. If we want to avoid the repetition, we should omit the informal statement of the theorem instead of the rigorous one. undo
