Graph of a quadratic

A quadratic function is a function that is shaped as a ___________, a u-shaped curve.

• line
• parabola
• quadratic
• square

Where the parabola (U shape) crosses the x-axis.

• Domain

• Range

• Y-intercept

• X-intercept

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

Where the parabola crosses the y-axis.

• X-intercept

• Domain

• Y-intercept

• Axis of Symmetry

Standard form of a quadratic equation

• y=x²
• y=ax²+bx+c
• y=mx+b
• y=x

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

Does this graph have a maximum or minimum value?

• maximum
• minimum
• neither
• both

What is the green dashed line called?

• roots or x-intercepts

• parabola

• axis of symmetry

• y intercept
