Web358 Concavity and the Second Derivative Test There is an interesting link between concavity and local extrema. Sup-pose a function f has a critical point c for which f0(c) = 0.Observe (as illustrated below) that f has a local minimum at c if its graph is concave up there. And f has a local maximum at c if it is concave down at c. y= f(x) 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. klutch screw extractor and drill bit setWebConcave Up.

WebRecall that a function is concave up when its second derivative is positive, which is when its first derivative is increasing. In (a) we saw that the acceleration is positive on \((0,1)\cup(3,4)\text{;}\) as acceleration is the second derivative of position, these are the intervals where the graph of \(y=s(t)\) is concave up. WebMar 26, 2016 · A positive second derivative means that section is concave up, while a negative second derivative means concave down. And where the concavity switches from up to down or down to up (like at A and B), you have an inflection point, and the second derivative there will (usually) be zero. Practice questions
