If y = f (x) is the cubic, and if you know how to take the derivative f '(x), do it again to get f ''(x) and solve f ''(x) = 0 for x; the inflection point of the curve is at (x,f (x)). The 2nd derivative measures the concavity, down or up, and the inflection point …. To identify the inflection point, I calculate (first the first derivatives and then) the second derivative of the spline coefficients ( the polynomial derivatives is f''(x) = 6ax + 2b ). An inflection point is a point where the graph of a function changes concavity from concave up to concave down, or vice versa. Find their y-coordinates, and add them to your graph. We use inflection points to help us determine the where concavity changes. A point where the derivative of the function is zero but the derivative does not change sign is known as a point of inflection, or saddle point.
