Question 1:  Given the graph of the function

a.  What is the vertex of the parabola: 

b.  Is this vertex a maximum or minimum value for the function ?

­­­­­­­c.  How do you know that it is a minimum or maximum?

d.  What are the zeros/solutions to the equation ?

e.  Explain how the zeros/solutions can be found by looking at the graph.

f.   Explain how the zeros/solutions can be found without graphing .

Question 2 Solve the equation:  and describe the steps used. (Remember when solving radical equations you must check your solution.)  

Question 3: 

Given the parent graph A:
