Polynomial Functions Lesson 6-1 Additional Examples Write each polynomial in standard form. Then classify it by degree and by number of terms. a. 9 + x3 b.x3 – 2x2 – 3x4 –3x4 + x3 – 2x2 x3 + 9 The term with the largest degree is x3,so the polynomial is degree 3. The term with the largest degree is –3x4, so the polynomial is degree 4. It has two terms. The polynomial is a cubic binomial. It has three terms. The polynomial is a quartic trinomial.

Enter the data. Use the LinReg, QuadReg, and CubicReg options of a graphing calculator to find the best-fitting model for each polynomial classification. Graph each model and compare. The quadratic model appears to best fit the given values.
