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

The vertex is... 

• The highest point or the lowest point of the parabola 
• The imaginary line that divides the parabola in half 
• The point where the graph crosses the x-axis
• The point where the graph crosses the y-axis
