How to determine concavity

WebDec 28, 2024 · Determine the t - intervals on which the graph is concave up/down. Solution Concavity is determined by the second derivative of y with respect to x, \frac {d^2y} {dx^2}, so we compute that here following Key Idea 38. In Example 9.3.1, we found \frac {dy} {dx} = \frac {2t+6} {10t-6} and f^\prime (t) = 10t-6. So: WebMar 26, 2016 · Because the concavity switches at x = 1 and because equals zero there, there's an inflection point at x = 1. Find the height of the inflection point. Thus f is concave up from negative infinity to the inflection point at (1, –1), and then concave down from there to infinity. As always, you should check your result on your graphing calculator.
