1. WARM - UP 1.Given the following information sketch a graph of the polynomial: 2.Find all of the roots of the following polynomial:

2. WRITING POLYNOMIALS GIVEN THE ROOTS -NOTES -PRACTICE

3. STEPS: Write each zero has a factor x=#, and move the # to the other side put in ( ) Multiply each factor together [distribute] Check that the degree matches the number of zeros you had to begin with! Plug function into calculator and check for rational roots in table! ***Remember: i come in pairs!!!***

4. FIND THE POLYNOMIAL WITH THE GIVEN ROOTS:

5. ***You always want to multiply the radicals or imaginaries together FIRST!

6. FIND THE POLYNOMIAL WITH THE GIVEN ROOTS: ***You always want to multiply the radicals or imaginaries together FIRST!

7. FIND THE POLYNOMIAL WITH THE GIVEN ROOTS:

8. FINDING THE INTERSECTION OF POLYNOMIALS GRAPHICALLY SUBSTITUTION

9. Find the intersection using substitution.

10. DETERMINE THE NUMBER OF POINTS OF INTERSECTION GRAPHICALLY 1 or 2

11. NOW, DETERMINE THE POINTS OF INTERSECTION WITH THE GRAPHING CALCULATOR

12. Find the intersection using a graphing calculator.

13. Find the intersection using the graphing calculator.
