Parts of Parabolas Practice

Front

What is a parabola?

Back

A parabola is a U-shaped curve that is the graph of a quadratic function. It can open upwards or downwards.

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is y = ax² + bx + c, where a, b, and c are constants.

Front

What is the vertex of a parabola?

Back

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

Front

What is the y-intercept of a parabola?

Back

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

Front

How do you find the y-intercept from a quadratic equation?

Back

To find the y-intercept, set x = 0 in the equation and solve for y.

Front

What is an x-intercept?

Back

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

Front

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

Back

To find the x-intercepts, set y = 0 in the equation and solve for x.

Front

What does the axis of symmetry represent 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 significance of the ordered pair (0, -2) in a parabola?

Back

The ordered pair (0, -2) represents the y-intercept of the parabola.

Front

What is the significance of the ordered pair (2, -4) in a parabola?

Back

The ordered pair (2, -4) represents the vertex of the parabola.
