1. The degree of a polynomial in one variable is the greatest exponent of its variable. The leading coefficient is the coefficient of the term with the greatest degree.

2. Is the expression a polynomial in one variable? If it is, state the degree and leading coefficient. Yes; degree: 4 leading coefficient: 1 No; It contains two variables, a and b. No; The term 2c–1 is not a monomial (dividing by the variable c). Example 1-1a

3. 2 Find 2 2 2 2 = 32 – 8 + 6 = 30 Find Example 1-3a

4. Find = 2(4x2 – 4x + 1) + 2x – 1 – 1 Example 1-3b

5. Graphs of polynomial functions Example: f(x) = 4

6. Example: f(x) = 2x + 3

7. Example: f(x) = x2 – 2

8. Example: f(x) = x3 + 2x

9. Example: f(x) = x4 + 2x3 + 5

10. Example: f(x) = x5 + 3x3 + 5x

11. If leading coefficient is negative, left side will be up. End behavior? Ends move in opposite directions (one up, one down) Odd-degree functions

12. Even-degree functions If leading coefficient is negative, both sides will be down End behavior? Ends move in same direction (both up or both down)

14. State the number of real zeros NONE

15. Describe the end behaviorExample 1-4a

17. State the number of real zeros 3

18. Describe the end behaviorExample 1-4a

20. State the number of real zeros two

21. Describe the end behaviorExample 1-4a
