Quadratic Function Vocabulary

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, represented by the coordinates (0, y).

Front

What is the standard form of a quadratic function?

Back

Front

What is the axis of symmetry in a parabola?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, passing through the vertex.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point on the graph of a quadratic function, depending on its orientation.

Front

What shape does the graph of a quadratic function take?

Back

The graph of a quadratic function is called a parabola.

Front

Back

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

Front

What is the maximum value of a quadratic function?

Back

The maximum value is the highest point on the graph of a quadratic function, occurring at the vertex if the parabola opens downward.

Front

What is the minimum value of a quadratic function?

Back

The minimum value is the lowest point on the graph of a quadratic function, occurring at the vertex if the parabola opens upward.

Front

How do you find the x-intercepts of a quadratic function?

Back

The x-intercepts can be found by setting the quadratic equation to zero and solving for x.
