How to Locate Intervals of Concavity and Inflection Points

WebWe call the graph below concave down. Figure 2 Definition of Concavity. Let f ' be the first derivative of function f that is differentiable on a given interval I, the graph of f is (i) concave up on the interval I, if f ' is increasing on I , or (ii) concave down on the interval I, if f ' is decreasing on I. WebNow that we know the intervals where f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f is concave down before x=-1 x = −1 , concave up after it, and is defined at x=-1 x = −1 . So f f has an inflection point at x=-1 x = −1 . f f is concave up before and after x=0 x = 0
