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 When the sign of the first derivative ie of the gradient is the same on both sides of a stationary point then the stationary point is a point of inflection A point of inflection does not have to be a stationary point however
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 Learn about inflection points and how to find them using differential calculus

If is an inflection point then 0 or is undefined and the curve is continuous and changes from concave upward to downward or vice versa at To find the points of inflection we will The first dervative is f x 3x 2 1 and the second is f x 6x Since f 0 0 there is potentially an inflection point at zero Since f x 0 when x 0 and
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 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
