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 formula for the axis of symmetry is:

• y = b² - 4ac

• y = -b/2a

• x = b² - 4ac

• x = -b/2a

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

• the vertex

• the maximum

• a parabola

• the minimum

The turning point of the quadratic graph is called the:

• vertex

• minimum

• maximum

• axis of symmetry

0 = x^2 - 9

• x = 0 or x = 3

• x = -3 or x = 3

• x = -9 or x = 0

• x = 0 or x = 9
