A parabola has a vertex at (-3,2).
Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2

What is the "formula" for finding the axis of symmetry?

• x = -4

• x = 4

• y = 4

• y = -4

• Axis of Symmetry: x = 10 Vertex: (10, -28)

• Axis of Symmetry: x = 5 Vertex: (5, -3)

• Axis of Symmetry: x = -5 Vertex: (-5, -103)

• Axis of Symmetry: x = 5 Vertex: (5, 47)

For the given graph, find

Vertex = ​ (a)  

Axis (line) of symmetry ​ (b)  

• x=-4

• (-3,-1)

• (3, -1)

• x=-3

• x=3

• (-4, -2)

Find the axis of symmetry and vertex

• x=3 (3,-3)

• x=4, (4,-4)

• x= -4, (-4,4)

• x=-4 (-4, 60)

Identify the axis of symmetry.

• x=-1

• x=4

• x=3

The vertex of the parabola is at ​ (a)   . This means there is a ​ (b)   value at ​ (c)  

• (1,5)

• Maximum

• y = 5

• (5, 1)

• Minimum

• y = 1

• (0, 4)
