• 0, 3, 4, 3, 0

• 0, -3, -4, -3, 0

• -2, -1, 0, 1, 2

• 2, 1, 0, -1, -2

What is the axis of symmetry? Remember the formula -b/2a

y = 3x² - 6x + 4

• x=1

• x=-6

• x=2

• x=-1

How do you find the vertex of the parabola?

• Identify the a, b and c of the given equation.

• Solve for y

• Plug in x - value to the given equation.

• Solve for x.

• Axis of symmetry: x = 0; Vertex: (0, -4)
• Axis of symmetry: x = 0; Vertex: (0, -2)

• Axis of symmetry: x = -2; Vertex: (-2, -4)
• Axis of symmetry: x = -2; Vertex: (-2, 0)

Plot the positive parabola by placing the y-intercept at y=-3 and the vertex at (2,-4)
