On what interval is f concave downward
http://mathsfirst.massey.ac.nz/Calculus/Sign2ndDer/Sign2DerPOI.htm Web21 de nov. de 2012 · Below x = -2, the value of the second derivative, 30x + 60, will be negative so the curve is concave down. For higher values of x , the value of the second derivative, 30x + 60 , will be positive so the curve is concave up. We can conclude that the point (-2,79) is a point of inflection. Consider f(x) = x4.

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.
