The highest power of the variable that occurs in the polynomial is called the degree of a polynomial. If the variable in a term is multiplied by a number, then this number is called the "coefficient" (koh-ee- FISH -int), or "numerical coefficient", of the term. 9 x y 2 - 9 x y 2. The degree of a polynomial function helps us to determine the number of x-intercepts and the number of turning points.A polynomial function of nth degree is the product of n factors, so it will have at most n roots or zeros, or x-intercepts.The graph of the polynomial function of degree n must have at most n - 1 turning points. Get detailed, expert explanations on coefficients of polynomials that can improve your comprehension and help with homework. Read More. Lennox Math. The exponent says that this is a degree- 4 polynomial; 4 is even, so the graph will behave roughly like a quadratic; namely, its graph will either be up on both ends or else be down on both ends.
