Axis of Symmetry and Vertex from the Graph

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

• y = -2

• x = 3

• x = -3

• y = 2

A vertical line that cuts the parabola into halves. This always goes through the vertex and ALWAYS begins with "x=".

• Parabola

• Quadratic

• Axis of Symmetry

• Domain

The highest or lowest point on the parabola

• Parabola

• Domain

• Vertex

• Range

The maximum or minimum point of a parabola, the point the axis of symmetry cuts through, is called

• point of inflection

• origin

• vertex

• starting point

The axis of symmetry is _____________________ .

Identify the vertex and whether the graph opens up or down.

• (-1, 4); opens up

• (-1, 4); opens down

• (1, 4); opens up

• (1, 4); opens down

Which best describes the vertex of a parabola?

• Any point on the parabola.

• A point on the x-axis.

• The highest or lowest point of a parabola

• A point on the y-axis.

A vertical line that cuts the parabola into 2 symmetrical halves. This always goes through the vertex and ALWAYS begins with "x=" This is sometimes called the "line of symmetry".

If "a" from y = ax² + bx + c is negative, then the vertex is the highest point on the graph.

• Maximum

• Vertex

• Minimum

• Parabola

What is the green dashed line called?

• roots or x-intercepts

• parabola

• axis of symmetry

• line of dashes
