2. What goes up??? ….
….MUST COME DOWN!

4. To start graphing PARABOLA’s, you make a T-Chart… but what numbers do you pick for the x’s???
You FIND THE VERTEX
X= , Y=

5. Now you pick numbers that are smaller than the VERTEX “x” and bigger than the VERTEX “x”.
HOW DO YOU FIND “x” again????

13. HOMEWORK Page 475 : # 11, 13, 15 FINISH THE TABLE OF (5) VALUES
VERTEX GOES IN MIDDLE!

14. Copy then complete the function table using the rule .1 2 3 4 5 6 7 8 13 6 1 -2 -3 -2 1 6 13
Use your ID card to draw, scale and label a set of axes on your paper!
Plot the points from the table onto your graph.

16. On your graph
Make sure you put arrows on the end of your graph
Write the equation next to the parabola
Label the vertex and write its coordinates
Circle and identify the roots
Draw the axis of symmetry and write its equation
Does the graph have a maximum or minimum? What is it?
Identify the domain and range
