Warmup
Warmup

  • Tell the number of possible positive, negative, and imaginary zeros for the following function:


Goals for today
Goals for today

  • Reminders:

    • Group quiz tomorrow—on new material through Descartes’ Rule of Signs

  • Essential Question/New Material


Essential question
Essential Question

  • How do I find the roots of a polynomial function?

  • How do I determine an equation and graph of a polynomial function given its roots?


Rational zero theorem
Rational Zero Theorem

  • Use Descartes’ Rule of Signs to identify the number of possible positive and negative zeros.

  • Use handout for notes and examples on the Rational Zero Theorem.


Writing equations from roots
Writing equations from roots

  • When you know ALL the roots of an equation, write the FACTORS and multiply them together.

    • EXAMPLE: Given these roots, write the equation

    • Use the roots to write the factors and multiply them.
