What does the h term tell you?

• left or right

• left or right, opposite sign, axis of symmetry, x-value of the vertex.

• axis of symmetry, x-value of the vertex

• nothing.

What does the k term tell you?

• up.

• down.

• up/down, y-value in the vertex

• nothing

• a=-1, h=3, k=2

• a=3, h=3, k=3
