Convex and Concave

Convex and concave are terms used to describe the shapes of curves or surfaces in geometry, as well as in mathematical functions. Here's a breakdown of both concepts: ### Convex 1. **Geometry**: - A shape is convex if, for any two points within the shape, the line segment connecting these two points lies entirely within the shape. - In simpler terms, a convex shape bulges outward, and it does not have any indentations or "dents.
