**BOOK SUMMARY :**

In differential calculus an inflection point point of inflection flex or inflection british english inflexion citation needed is a point on a continuous plane curve at which the curve changes from being concave concave downward to convex concave upward or vice versa if the curve is the graph of a function y fx of differentiability class c 2 this means that the second an inflection point is an event that results in a significant change in the progress of a company industry sector economy or geopolitical situation and can be considered a turning point after an inflection point is a point on a curve at which the sign of the curvature ie the concavity changes inflection points may be stationary points but are not local maxima or local minima for example for the curve yx3 plotted above the point x0 is an inflection point the first derivative test can sometimes distinguish inflection points from extrema for differentiable functions fxinflection points an inflection point is where a curve changes from concave upward to concave downward or vice versa so what is concave upward downward in calculus an inflection point is a point on a curve where the curvature changes sign it is used in various disciplines including engineering economics and statistics to determine fundamental shifts in data
