How many extrema can a cubic function have

http://www.sosmath.com/algebra/factor/fac111/fac111.html WebOf course, a quintic function may have up to four local extrema (maximums or minimums), and it always has an inflection point (since the second derivative is a cubic, or third-degree polynomial, which must always change signs at some point). In this article, we’ll take a closer look at quintic functions and answer some common questions about them.
