Key features from Graph
Vertex - high or low point
Maximum - when vertex is the high point
Minimum - when vertex is the low point
Domain - Left to Right (x-axis)
Range - low to high (y-axis)

10
Multiple Choice
What is the vertex?
11
Multiple Choice
State the domain and range.
12
Vertex Form
Vertex (h,k)
When pulling out a coordinate - h is the opposite sign
Axis of symmetry - x=h, opposite sign

Transformations from Vertex Form
a - shows stretch/dilation and reflection
h - positive = left and negative = right
k - positive = up and negative = down

Factored Form
The x-intercepts are in parentheses
OPPOSITE sign
points are (-3,0) and (2,0)
Other names for x-intercepts are zeros and roots
