Quadratic Key Features Context

Find the axis of symmetry for the graph

• x = -1

• x = 1

• x = 3

• x = -1 , 3

Use the picture to find the vertex and axis of symmetry:

• Vertex (3,8) Axis x = 3

• Vertex (3,8) Axis y = 3

• Vertex (8,3) Axis x = 3

• Vertex (8,3) Axis y = 3

Which value is the vertex?

• (-4, 0)

• (-1, -9)

• (0, -8)

• (2, 0)

• (-1,-2)

• Min

• x=-2

• x=0

• (0,0)

• (-2,-1)

• Max

• x=2
