Front

What is the standard form of a quadratic equation?

Back

y = a(x - h)² + k

Front

How do you find the vertex from the standard form of a quadratic equation?

Back

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

Front

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

Back

What is the axis of symmetry for the parabola y = ax² + bx + c?

Back

x = -b/(2a)
