11.13-14 Quadratic Functions Vocabulary

Front

What is the point where a graph intersects the x-axis called?

Back

The point where a graph hits the x-axis is known as the x-intercept.

Front

What is the orange line in a quadratic graph called?

Back

The orange line is called the Axis of Symmetry.

Front

What is the maximum of a quadratic function?

Back

The maximum of a quadratic function is the highest point (vertex) on a graph when a parabola opens down; it is the point where the graph changes from increasing to decreasing.

Front

What is the minimum of a quadratic function?

Back

The minimum of a quadratic function is the lowest point (vertex) on a graph when a parabola opens up; it is the point where the graph changes from decreasing to increasing.

Front

What is the range of a quadratic function that opens upwards?

Back

The range of a quadratic function that opens upwards is y ≥ k, where k is the y-coordinate of the vertex.

Front

What is the vertex of a quadratic function?

Back

The vertex of a quadratic function is the point (h, k) where the graph changes direction; it is the maximum or minimum point.

Front

How do you find the axis of symmetry for a quadratic function in standard form?

Back

The axis of symmetry can be found using the formula x = -b/(2a) from the quadratic equation ax^2 + bx + c.

Front

What does it mean for a quadratic function to open upwards?

Back

A quadratic function opens upwards when the coefficient of x^2 (a) is positive, indicating that the vertex is a minimum point.

Front

What does it mean for a quadratic function to open downwards?

Back

A quadratic function opens downwards when the coefficient of x^2 (a) is negative, indicating that the vertex is a maximum point.

Front

What is the standard form of a quadratic function?

Back

The standard form of a quadratic function is f(x) = ax^2 + bx + c, where a, b, and c are constants.
