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)

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?
