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 vertical line that divides your quadratic graph into two equal parts is called the (choose all that apply):

• line of symmetry

• axis of symmetry

• vertex

• foldline

The formula for the axis of symmetry is:

• y = b² - 4ac

• y = -b/2a

• x = b² - 4ac

• x = -b/2a

The turning point of the quadratic graph is called the:

• vertex

• minimum

• maximum

• axis of symmetry

The vertex that is the highest point of the graph is called the:

• minimum

• axis of symmetry

• maximum

• vertex

The vertex that is the lowest point of the graph is called the:

• vertex

• minimum

• maximum

• axis of symmetry

The point(s) at which the graph intersects the x-axis are called the:

• zeros

• x-intercepts

• solutions

• roots

Used to determine the number of solutions of a quadratic equation (choose all that apply):

• Discriminant

• axis of symmetry

• d = b² - 4ac

• x = - b/2a

The formula for the discriminant is:

• x = -b/2a

• y = -b/2a

• d = b² - 4ac

• y = ax² + bx + c
