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) WebDec 20, 2024 · Our definition of concave up and concave down is given in terms of when the first derivative is increasing or decreasing. We can apply the results of the previous section and to find intervals on which a graph is concave up or down. That is, we …

If then and concave up. If then and concave down. 7. Find the -values for the inflection points, points where the curve changes concavity. Plug the inflection points into the original function. 8. Write up the information. 1. Find the first derivative of the function: . 2. Find the second derivative of the function: 9. Graph the function.
WebA mnemonic for remembering what concave up/down means is: “Concave up is like a cup; concave down is like a frown.” It is admittedly terrible, but it works. Our definition of concave up and concave down is given in terms of when the first derivative is … WebSep 7, 2024 · To determine concavity, we need to find the second derivative f ″ (x). The first derivative is f ′ (x) = 3x2 − 12x + 9, so the second derivative is f ″ (x) = 6x − 12. If the function changes concavity, it occurs either when f ″ (x) = 0 or f ″ (x) is undefined. Since f ″ is defined for all real numbers x, we need only find where f ″ (x) = 0.
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
