A polynomial in. x is defined as a finite sum of terms of the form axn, where a is a real number and. the exponent nis a whole number. For each term,a is called the coefficient, and n. is called the degree of the term. For example: If a polynomial has exactly one term, it is categorized as a monomial. A two-. term polynomial is called a binomial, and a three-term polynomial is called a. trinomial. Usually the terms of a polynomial are written in descending order. according to degree. In descending order, the highest-degree term is written first.
As another respondent has said, a cubic polynomial has neither a global minimum or a global maximum. However it will usually have both a local minimum and maximum. To understand this, first note that local extrema (maxima or minima) occur where the first derivative is 0. This is the same as an x-intercept. You havenât specified exactly which cubic polynomial you have in mind, but the derivative will be a degree 2 polynomial. Three things can happen: The first derivative will have 2 roots. In that case, one of them will be a local maximum, the other a local minimum. The first derivative will have a single double root. The first derivative wonât change sign at the root, and so it will not be either a maximum or a minimum: just a level point.
