What is the standard form of a quadratic equation?

Back

y = ax^2 + bx + c, where a, b, and c are constants.

Front

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

Back

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

Front

What is the vertex form of a quadratic function?

Back

y = a(x-h)^2 + k, where (h, k) is the vertex.

Front

How do you find the vertex from the vertex form?

Back

The vertex is at the point (h, k).
