1) What table best represents this quadratic?

• 
• 
• 
• 

2) Factor the quadratic equation using the graph below.

• A. (x - 2)(x + 2) = 0
• B (x - 3)(x + 3) = 0
• C x(x - 4) = 0
• D x^2 - 4 = 0

3) What are the roots of the quadratic?

• A x = 2
• B x = -3 or x = 3
• C x = -2 or x = 2
• D x = -4 or x = 4

4) Find the y-intercept

• A The y-intercept is (0, -3).
• B The y-intercept is (0, -2).
• C The y-intercept is (0, -5).
• D The y-intercept is (0, -4).

5) Looking at the graph, what are the roots of the quadratic?

• A x = 48 or x = 64
• B x = 0
• C x = 1 or x = 3
• D x = 0 or x = 4

6) What is the y-intercept of the graph?

• A (0, 0)
• B (1, 48)
• C (3, 48)
• D (4, 0)

7) Determine the axis of symmetry.

• A The axis of symmetry is when x = 2.
• B The axis of symmetry is when x = 64.
• C The axis of symmetry is when x = 1.
• D The axis of symmetry is when x = 3.

8) Which equation best represents the axis of symmetry?

• A x = -b/2a; x = -(-4)/2(-1) = x = 4/-2 = x = -2. The axis of symmetry is when x = -2.
• B x = -b/2a; x = -(4)/2(-1) = x = -4/-2 = x = 2. The axis of symmetry is when x = 2.
• C x = -b/2a; x = -(128)/2(-1) = x = -128/-2 = x = 64. The axis of symmetry is when x = 64.
• D x = -b/2a; x = -(6)/2(-1) = x = -6/-2 = x = 3. The axis of symmetry is when x = 3.
