Talk about the axis of symmetry.  

How do you find it?  

Talk about at least 2 ways.  

Then try to think of how else you might be able to find it....

Can you see/find the axis of symmetry in each scenario?

Vertex is (­3, 5)

Zeros at (4, 0) and (6, 0)

Zeros at (­5, 0) and (2, 0)

Points (4, 1) and (8, 1)

Express the following in vertex form:  

y = ­2x2 + 24x ­ 64

Now this one...

Express the following in vertex form:  

y = ­3x2 + 12x + 29

We can't factor this, so we can't use the zeros to help us.

We could use two points that have the same y-coordinate, though! Why not start with the y-intercept?
