Concave Up and Concave Down: Meaning and Examples Outlier

WebIn order for 𝑓(𝑥) to be concave up, in some interval, 𝑓 ''(𝑥) has to be greater than or equal to 0 (i.e. non-negative) for all 𝑥 in that interval. The same goes for 𝑓(𝑥) concave down, but then 𝑓 ''(𝑥) is non-positive. 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.
