To find the points of inflection of a curve with equation y f x Examiner Tip Remember the first derivative ie the gradient does NOT have to be zero at a point of inflection The derivative is y 15x2 4x 3 The second derivative is y 30x 4 And 30x 4 is negative up to x 4 30 2 15 positive from there onwards So f x is concave downward up to x 2 15 f x is concave upward from x 2 15
A point of inflection is found where the graph or image of a function changes concavity To find this algebraically we want to find where the second derivative of the function changes sign Decide whether you have a minimum maximum or a point of inflection Calculate the value of the function at the x value for the point of inflection Example Find the point of inflection on

Finding Points of Inflection A point of inflection is a point where the shape of the curve changes from a maximum type shape d 2y dx 2 0 to a minimum type shape d 2y dx 2 0 Clearly the point of inflection will occur when Use concavity and inflection points to explain how the sign of the second derivative affects the shape of a function s graph Explain the concavity test for a function over an open interval Explain the relationship between a
A point x c is called an inflection point if the function is continuous at the point and the concavity of the graph changes at that point Now that we have all the concavity Learn how the second derivative of a function is used in order to find the function s inflection points Learn which common mistakes to avoid in the process
