1)     What is the rate of change function for the quadratic ?

ROC =

 

2)     How can the ROC function be used to find the x-coordinate of the vertex?

 

 

 

3)     Find the vertex (ordered pair!)

 

 

4)     Is the vertex a maximum or minimum?  HOW DO YOU KNOW?

 

 

 

5)     Where is the initial value for the original quadratic?  (ordered pair!)

 

 

6)     Use everything above to sketch a graph for the original quadratic
