This website uses cookies to ensure you get the best experience. If f and f' are differentiable at a. To find a point of inflection, you need to work out where the function changes concavity. The relative extremes of a function are maximums, minimums and inflection points (point where the function goes from concave to convex and vice versa). A critical point is a point on the graph where the function's rate of change is altered wither from increasing to decreasing or in some unpredictable fashion. Inflection points are where the function changes concavity. The points of inflection of a function are the points at which its concavity changes. Find the point of inflection on the curve of y = f(x) = 2x 3 − 6x 2 + 6x − 5. Therefore, inflection points are P1(, 5), P2(-, 5).
