What is the vertex of a parabola?

Back

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

Front

What are x-intercepts in a quadratic equation?

Back

X-intercepts are the points where the graph of the equation crosses the x-axis, represented as (x, 0).

Front

What does the ordered pair (2, -4) represent on a graph?

Back

It represents a point on the graph, specifically the vertex if it is the highest or lowest point.

Front

What is the significance of the vertex in a parabola?

Back

The vertex indicates the maximum or minimum value of the quadratic function.

Front

What are roots or zeros of a quadratic function?

Back

Roots or zeros are the values of x that make the quadratic equation equal to zero.

Front

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

Back

Set the quadratic equation to zero and solve for x.

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.

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of the form ax² + bx + c = 0, where a, b, and c are constants.

Front

What does the term 'y-intercept' mean?

Back

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

Front

How can you identify the vertex from a quadratic equation in standard form?

Back

The vertex can be found using the formula (-b/2a, f(-b/2a)).
