Transcript

  • 1. Evaluating and Graphing Polynomial Functions Algebra 2 6.2 p. 329
  • 2. Polynomials A polynomial is a function in the form
  • 3. Polynomials A polynomial is a function in the form is called the leading coefficient
  • 4. Polynomials A polynomial is a function in the form is called the leading coefficient is the constant term
  • 5. Polynomials A polynomial is a function in the form is called the leading coefficient is the constant term n is the degree of the polynomial
  • 6. Polynomials A linear function, like is a polynomial with degree one.
  • 7. Polynomials A linear function, like is a polynomial with degree one. A quadratic function, like is a polynomial with degree two.
  • 8. Polynomials Polynomials only have positive integer exponents.
  • 9. Synthetic Substitution Write the polynomial in standard form. This means the powers of x should be in descending order. If the polynomial is “missing” a power, put a zero in its place.
  • 10. Synthetic Substitution Write the polynomial in standard form. Write the coefficients of the terms.
  • 11. Synthetic Substitution Write the polynomial in standard form. Write the coefficients of the terms. Bring down the leading coefficient.
  • 12. Example
  • 13. Graphing End behavior: What the polynomial’s graph does at its ends.
  • 14. Graphing even
  • 15. Graphing odd even
  • 16. Graphing even odd even
  • 17. Graphing odd even odd even
  • 18. Graphing Figure out the end behavior.
  • 19. Graphing Figure out the end behavior. Make a table of values to figure out the middle.
