Finding Concavity and Points of Inflectio ... 1. Locate the points of inflection and use these numbers to determine test intervals. ... Determine the Concavity of the graph of f(x) = x4 - 4x3. Locate the points of inflection and use them as test intervals; f '(x) = 4x3 - 12x2; f ''(x) = 12x2 - 24x; 12x(x - 2) = 0;

Thus there are often points at which the graph changes from being concave up to concave down, or vice versa. These points are called inflection points. Since the monotonicity behavior of a function is related to the sign of its derivative we get the following result:

Finding Inflection Points with Maple ... A point at which the graph of a function changes concavity is called an inflection point. We can find this point by looking for a point where f'( x ) has a local minimum or a local maximum and where f''( x ) changes sign. ... TITLE>Inflection Points on Maple...
