What is the standard form of a quadratic function?

Back

f(x) = ax^2 + bx + c, where a, b, and c are constants.

Front

What is the factored form of a quadratic function?

Back

f(x) = a(x - r1)(x - r2), where r1 and r2 are the roots.

What is the axis of symmetry in a parabola?

Back

The vertical line that passes through the vertex, given by x = -b/(2a).

Front

What does the 'a' value in the standard form of a quadratic function indicate?

Back

It indicates the direction of the parabola (upward if a > 0, downward if a < 0) and the width of the parabola.
