1. Notes Day 6.1 Classify Polynomials Study End Behavior Fundamental Theorem of Algebra

2. Classify Polynomials 1 0 Constant Monomial 1 2 Binomial Linear 2 1 Monomial Quadratic 3 3 Cubic Trinomial 4 2 Quartic Binomial 5 4 Quintic Polynomial

3. Polynomial Graph End Behavior SAME Even: Left end __________ behavior Odd: Left end ____________ behavior Assume this is the leading term of a polynomial in standard form. OPPOSITE axn n – 1 __________ max turns UP Positive: Right end _____________ Negative: Right end ____________ DOWN

4. Up 2 Down 3 Down Down Up Down 2

5. Which is possible for this graph according to end behavior? y= -3x5 + 4x + 1 y = -2x4 + 1 y = 3x2 + 4x + 1 y = 2x5 + 4x + 1

6. Write a polynomial function in standard form with zeros at -2,-5, and 3. Then classify it by degree and term. (x+2) (x+5) (x – 3) Y = X3 + 4x2 – 11x – 30 (x2 + 7x + 10) (x – 3) Cubic Polynomial • GRAPH THIS ON BACK OF YOUR NOTES… • Plot roots • Use leading term to identify end behavior • Use 2nd trace to find max and min between roots 10x 7x2 x3 -30 -21x -3x2

7. FundamentalTheorem of AlgebraThe roots of polynomial functions are complex numbers Irrationals Rationals Integers Wholes Counting ½ , -3.4, 1/3 -2, -1, 0, 1, 2, 0, 1 ,2 ,3 ,4 ,… 1 ,2 ,3 ,4 ,…

8. Draw a possible quartic function with a negative leading coefficient, 2 real roots at and a y-intercept of 2. The last part of the graph can vary greatly! Due to quartic (4th degree – there can be a max of 3 turns

9. Review Parent Functions / Shifts D: [-1,∞) R: [-2,∞) Yes (-1,-2) D: (-∞,∞) R: (-∞ -5] (4,-5) Yes D: (-∞,∞) R: [-4,∞) Yes (3,-4) D: (-∞,∞) R: (-∞,∞) Yes
