Identifying Key Features on a Quadratic Graph

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• symmetrical point for the vertex

Name the vertex

• (1,1)

• (0,0)

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

Does the graph have a maximum or minimum?

• maximum

• minimum

• neither

• both

Where the parabola crosses the y-axis.

• X-intercept

• Domain

• Y-intercept

• Axis of Symmetry
