Finding the Vertex and Axis of Symmetry

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 green dashed line called?

• roots or x-intercepts

• parabola

• axis of symmetry

• line of dashes

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

• x = -4

• x = 4

• y = 4

• y = -4

For the given graph, find

Vertex = ​ (a)  

Axis (line) of symmetry ​ (b)  

• x=-4

• (-3,-1)

• (3, -1)

• x=-3

• x=3

• (-4, -2)

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)

The function has a ​ (a)   with a value of ​ (b)   and the equation for the axis of symmetry is ​ (c)  

• minimum

• -5

• x=-3

• y=-5

• maximum

• -3

• -4

• 4

• x=-5

• x=3

The vertex of the graph is ​ (a)   and the axis of symmetry is ​ (b)   .

• (6,-6)

• Vertex

• 6

• (3,5)

• y-inetrcept

• (y,x)

• y

• -6

• (h,K)

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
