Algebra II Section 3.1 Polynomials

Warm-up Pg 147 #1-13

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

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

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

Try these! Pg 154 #2-9

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

Try these! Pg. 154 #10-13

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

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

Try these Pg. 154 #15-18
