The critical points of a cubic function are its stationary points, that is the points where the slope of the function is zero. Thus the critical … See more

The graph of a cubic function is a cubic curve, though many cubic curves are not graphs of functions.
Although cubic functions depend on four parameters, their graph can have only very few shapes. In fact, the graph of a cubic function is … See more

Given the values of a function and its derivative at two points, there is exactly one cubic function that has the same four values, which is called a cubic Hermite spline See more

For a cubic function of the form $${\displaystyle y=x^{3}+px,}$$ the inflection point is thus the origin. As such a function is an odd function, its graph is symmetric with respect to the inflection point, and invariant under a rotation of a half turn around the … See more
