Web1 de mar. de 2024 · So the graph is concave up in the interval 0 < x < 2. From 2 < x < 3 the graph is opening downwards. So the graph is concave down in the interval 2 < x < 3. For a smooth graph (do you know what this means?) an inflection point always lies between concave up and concave down segments. WebExample 1. Find the inflection points and intervals of concavity up and down of. f ( x) = 3 x 2 − 9 x + 6. First, the second derivative is just f ″ ( x) = 6. Solution: Since this is never zero, there are not points of inflection. And the value of f ″ is always 6, so is always > 0 , so the curve is entirely concave upward.
