1. Algebra II
Section 3.1
Polynomials

2. Warm-up
Pg 147 #1-13

3. Recall the definitions for:
Monomial
Binomial
Trinomial
Polynomial-a monomial or a sum of monomials

4. Degree of a monomial-the sum of the exponents of the variables
Degree of a polynomial- determined by the term with the greatest degree

5. Writing a polynomial in one variable in standard form- terms are written in descending order by degree

8. Try these!
Pg 154 #2-9

9. Adding or Subtracting Polynomials
#1 Eliminate parentheses
#2 Combine like terms
Write terms in descending order

12. Try these!
Pg #10-13

13. Polynomial function- a function whose rule is a polynomial
Which parent functions have rules that are polynomials?

14. Linear functions have no turns and a maximum of 1 x-intercept
Quadratic functions have 1 turn and a maximum of 2 x-intercepts (zeros)
Cubic functions have two turns and a maximum of 3 zeros
This pattern continues

15. Try these
Pg. 154 #15-18

16. Classwork/homework
Pg 154 #19-30,36-39,41-44 (if you don’t remember these from Geometry, google), 54-57
