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

• y = -2

• x = 3

• x = -3

• y = 2

The axis of symmetry for a vertical parabola always matches...

• the y-intercept

• the y-value of the vertex

• the x-value of the vertex

• the x-intercepts

For the given graph, find

Vertex = ​ (a)  

Axis (line) of symmetry ​ (b)  

• x=-4

• (-3,-1)

• (3, -1)

• x=-3

• x=3

• (-4, -2)

What is the vertex and the axis of symmetry in the following equation: y = -x^2 - 4x - 2

• x = -2; (-2, 2)

• x = -2; (-2, 10)

• x = 2; (2, -6)

• x = 2; (2, 14)

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 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)
