Algebra Quiz 3 – SB Name: Date: 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 Graphing linear inequalities and equations 1. 1.
