Quadratic Equations Quiz

The standard form of a quadratic equation is:

• y = ax² + bx + c

• x = -b/2a

• y = a(x - h)² + k

• d = b² - 4ac

The U-shaped graph created by a quadratic equation is:

• the vertex

• the maximum

• a parabola

• the minimum

The formula for the axis of symmetry is:

• y = b² - 4ac

• y = -b/2a

• x = b² - 4ac

• x = -b/2a
