The image displays a question asking whether the figure is convex or not convex. The figure in question appears to resemble an "hourglass" or "bow-tie" shape, which includes inwardly curving sides.

### Convexity Concept:
A **convex** shape is one where, for any two points inside the shape, the line segment connecting them lies entirely within the shape. If there are any points where this condition fails, the shape is considered **non-convex**.

### Analysis:
In the given figure, it has inward indentations. This means that if you pick two points inside the shape near these indentations, the line connecting them will pass outside the shape. Therefore, the figure is **not convex**.

### Conclusion:
The correct answer is **"not convex."**
