Vocab:Def. Tips:
Axis of Symmetry (A of S)
Where the parabola splits into two equal halves
Use to find axis
Vertex
Exact top point or bottom point of a parabola
x coord. will always be the axis of symmetry
Maximum (max)
Vertex if parabola is upside down
You will see
Minimum (min)
Vertex if parabola is right side up
You will see
