Quadratic Functions and Vertex Form
1. The vertex form of a quadratic equation is:
[A] y = a(x – h)2 + k
[B] y = a(x – h)2 – k
[C] y = a(x – h) + k
[D] y = a(x – h) – k
1. Answer
2. The k in the vertex form of the equation does this to the parabola:
[A] Vertical movement of the vertex
[B] Flips the parabola over the x-axis
[C] Horizontal movement of the vertex
[D] Nothing, doesn’t change the parabola
2. Answer
3. The h in the vertex form of the equation does this to the parabola:
[A] Vertical movement of the vertex
[B] Flips the parabola over the x-axis
[C] Horizontal movement of the vertex
[D] Nothing, doesn’t change the parabola
3 Answer
4. The a in the vertex form of the equation does this to the parabola:
[A] Vertical movement of the vertex
[B] Flips the parabola over the x-axis
[C] Horizontal movement of the vertex
[D] Nothing, doesn’t change the parabola
4. Answer
5. The vertex of a quadratic equation in vertex form can be stated as:
[A]
(k, h)
[B]
(h, k)
[C]
(h, a)
[D]
(a, h)
5. Answer
6.
6. Answer
The minimum point of the parabola is:
[A}
(-4, 0)
[B]
(0, -4)
[C]
(-1.5, -4)
[D]
(1.5, -4)
The vertex form of a quadratic equation is:
y = a(x – h)2 + k
y = a(x – h)2 – k
y = a(x – h) + k
y = a(x – h) – k
