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

Back

The direction of the parabola (upward if positive, downward if negative).

Front

What is the vertex of a parabola in vertex form?

Back

The point (h, k) in the equation y = a(x-h)^2 + k.

Front

How do you convert from vertex form to standard form?

Back

Expand y = a(x-h)^2 + k to y = ax^2 + bx + c.

What is the axis of symmetry (AOS) in a quadratic function?

Back

The vertical line x = h, where h is from the vertex form y = a(x-h)^2 + k.
