Front

Define a quadratic function.

Back

A polynomial function of degree 2, typically in the form f(x) = ax^2 + bx + c.

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax^2 + bx + c.

Front

What does the vertex of a parabola represent?

Back

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

Front

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

Back

Use the formula x = -\frac{b}{2a} to find the x-coordinate, then substitute back to find the y-coordinate.

Front

What is the axis of symmetry in a parabola?

Back

A vertical line that divides the parabola into two mirror-image halves, given by x = -\frac{b}{2a}.
