Front

What is the vertex of a quadratic function?

Back

The highest or lowest point of the parabola.

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c, where a, b, and c are constants.

Front

What does the 'a' value in a quadratic function determine?

Back

The direction of the parabola (upward if a > 0, downward if a < 0).

Front

What is the axis of symmetry in a quadratic function?

Back

The vertical line that divides the parabola into two mirror images, given by x = -b/(2a).

Front

What are the x-intercepts of a quadratic function?

Back

The points where the graph intersects the x-axis, also known as the zeros or roots.
