Introduction to Parabola

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".

• Parabola

• Quadratic

• Axis of Symmetry

• Domain

The vertex is defined as:

• The maximum.

• The minimum.

• The highest or lowest point of the parabola.

• The vertical height of the parabola

If the vertex is the highest point of the parabola, it is called a _______________.

• valley

• peak

• minimum

• maximum

If the vertex is the lowest point of the parabola, it is called a ________________.

• valley

• peak

• minimum

• maximum

What is the vertex?

• (4,-4)

• (2,0)

• (0,2)

• (6,0)

What is the green dot on this parabola called?

• vertex

• root

• zero

• solution

Does the quadratic have a max/min vertex, and does the parabola open up/down?

• max/ opens down

• min/ opens up

• max/ opens up

• min/ opens down

The axis of symmetry is a line that goes through the...

• y-intercept

• any random point

• vertex

•  x-axis or y-axis

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.

How many roots does this parabola have? 

• 3

• 2

• 0

• 1
