Front

Define a parabola.

Back

A parabola is a symmetric curve formed by the intersection of a cone with a plane parallel to its side.

Front

What is the standard form of a quadratic function?

Back

f(x) = ax² + bx + c, where a, b, and c are constants.

Front

How do you find the vertex of a parabola in standard form?

Back

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

Front

What does the 'a' value in the quadratic equation affect?

Back

The 'a' value determines the direction and width of the parabola.

Front

What are the x-intercepts of a parabola?

Back

The points where the parabola crosses the x-axis.
