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

6. Algebra 2 xy 02.8 25 46 65.5 84 Using a graphing calculator, determine whether a linear, quadratic, or cubic model best fits the values in the table. Lesson 6-1 Polynomial Functions 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. Linear modelQuadratic modelCubic model Additional Examples
