Domain and Range: Quadratic

Front

What is the definition of Domain in a quadratic function?

Back

The set of all possible x-values (inputs) for which the function is defined.

Front

What is the definition of Range in a quadratic function?

Back

The set of all possible y-values (outputs) that the function can produce.

Front

How is the Range of a quadratic function determined?

Back

The Range is found from the lowest point (minimum) to the highest point (maximum) of the parabola.

Front

What is the Vertex of a parabola?

Back

The highest or lowest point on the parabola, which represents the maximum or minimum value of the function.

Front

How do you find the Domain of a quadratic function?

Back

The Domain is typically all real numbers unless there are restrictions.

Front

What does it mean if a quadratic function opens upwards?

Back

It means the vertex is the minimum point, and the Range starts from the y-coordinate of the vertex to positive infinity.

Front

What does it mean if a quadratic function opens downwards?

Back

It means the vertex is the maximum point, and the Range starts from negative infinity to the y-coordinate of the vertex.

Front

What is the standard form of a quadratic function?

Back

Front

What is the significance of the coefficient 'a' in a quadratic function?

Back

The coefficient 'a' determines the direction of the parabola (upward if a > 0, downward if a < 0) and affects the width of the parabola.

What is the axis of symmetry in a quadratic function?
