WebConcavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity. WebConvexity downward can also be characterized by the fact that the arc of the curve lies no lower than the tangent at any of its points, and concavity downward by the fact that the …
