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".

The vertex is defined as:

• The maximum.

• The minimum.

• The highest or lowest point of the parabola.

• The vertical height of the parabola

• 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?
