Quadratic Characteristics From Graphs

Front

What is the range of a quadratic function that opens downwards with a vertex at (0, 4)?

Back

All real numbers less than or equal to 4.

Front

What shape is the graph of a quadratic function?

Back

U shaped.

Front

Using the graph of the quadratic function, identify the range if the vertex is at (0, -6).

Back

y >= -6.

Front

What divides the parabola into 2 perfect halves?

Back

Axis of Symmetry.

Front

The graph of a quadratic is called a?

Back

Parabola.

Front

What is the vertex of a quadratic function?

Back

The highest or lowest point of the parabola.

Front

What is the axis of symmetry in a quadratic function?

Back

A vertical line that divides the parabola into two mirror-image halves.

Front

What are the x-intercepts of a quadratic function?

Back

The points where the graph intersects the x-axis.

Front

What is the standard form of a quadratic function?

Back

y = ax^2 + bx + c.

Front

What does the 'a' in the quadratic equation y = ax^2 + bx + c determine?

Back

The direction and width of the parabola.
