• vertex
• parabola
• roots or x-intercepts

What is the equation for axis of symmetry?

• x=1

Does this parabola have a maximum or minimum?

• Maximum
• Minimum

What are the x-intercepts of the parabola?

y = -3(x + 5)(x - 9)

• (-5, 0) and (9, 0)

• (5,0) and (-9, 0)

• (5, 0) and (9, 0)

• (-3, 0) and (5, 0)and (-9, 0)

What are the x-intercepts of the parabola?

y = ¼(x + 2)(x - 6)

• (-2, 0) and (6, 0)

• (2, 0) and (-6, 0)

• (-2, 6)

• (¼, 0) and (-2, 0) and (6, 0)

What are the x-intercepts of the parabola?

y = x(x - 4)

• (0, 0) and (4, 0)

• (0, 4)

• (-4, 0) and (0, 0)

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing.

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• symmetrical point for the vertex

What is the equation of this graph?

• f(x) = (x -5)² + 1

• f(x) = (x - 1)² - 5

• f(x) = (x + 1)² - 5

• f(x) = (x + 5)² +1

A parabola has a vertex at (-3,2).

Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2
