- 1. Multiple Choice
Which equation best represents the graph?y = 2(x - 4)2 + 5y = 2(x + 4)2 + 5y = -2(x - 4)2 + 5y = -2(x + 4)2 + 5 - 2. Multiple ChoiceWhat is the vertex form of this quadratic?f(x) = -(x + 2)2 - 4f(x) = (x - 2)2 + 4f(x) = (x - 2)2 - 4f(x) = -(x - 2)2 - 4
- 3. Multiple ChoiceWhich equation represents this graph.f(x)=(x - 4)2 - 3f(x)=-(x - 4)2 + 3f(x)=(x - 4)2 + 3f(x)=-(x + 4)2 + 3
- 4. Multiple ChoiceWhat is the vertex form for a vertex of (-3,-5) and when a=-2?y = -2(x-3)2+5y = -2(x+3)2+5y = -2(x+3)2-5
- 5. Multiple ChoiceWrite the equation of the quadratic in vertex form given the following:
vertex: (4, -2)
point: (0,-6)
opens downf(x)=(x-4)2-2f(x)=-4(x-4)2-2f(x)=1/4(x+4)2-2f(x)=-1/4(x-4)2-2 - 6. Multiple ChoiceWhich Quadratic function has a vertex at (-2,7) and opens down?y = -3(x + 2)2 + 7y = (x - 2)2 + 7y = -12(x + 2)2 - 7y = -2(x - 2)2 + 7
