WebIf the point is either less than zero, or between zero and 5/2, the derivative evaluates to a negative number, which means the slope of the function evaluated at those points is negative, so the slope is negative, hence the function is decreasing in those intervals, which is what we were asked to find. Keep Studying! Web3 de ago. de 2015 · It's clear that f will be negative on this interval, so f will be concave down. ( − 1,1) On this interval, f will be positive, since (x2 −1) will be negative. As a result, f will be concave up. (1,∞) Once again, f will be negative for this interval, so f will be concave down. Answer link daly gentry designs

Web1 de mar. de 2024 · So the graph is concave up in the interval $0<2$. From $2<3$ the graph is opening downwards. So the graph is concave down in the interval $2<3$. For a smooth graph (do you know what this means?) an inflection point always lies between concave up and concave down segments. WebNow that we know the intervals where f f f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f f f is concave down before x = − 1 x=-1 x = − 1 x, equals, minus, 1 , concave up after it, and is defined at x = − 1 x=-1 x = − 1 x, equals, minus, 1 .

WebIf the interval is positive then this tells us the interval is concave up. Similarly, if the interval is negative then this tells us the interval is concave down. So in our example, our function is concave up on the interval (−∞,1) and our function is concave down on the interval (1,∞).
