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 … WebMar 26, 2016 · For f ( x) = –2 x3 + 6 x2 – 10 x + 5, f is concave up from negative infinity to the inflection point at (1, –1), then concave down from there to infinity. To solve this problem, start by finding the second derivative. Now set it equal to 0 and solve. Check for x values where the second derivative is undefined. (There are none.) WebConcave up on (0,∞) ( 0, ∞) since f ''(x) f ′′ ( x) is positive The graph is concave down when the second derivative is negative and concave up when the second derivative is positive. Concave down on (−∞,0) ( - ∞, 0) since f ''(x) f ′′ ( x) is negative Concave up on (0,∞) ( 0, ∞) since f ''(x) f ′′ ( x) is positive is america a go place to live
