- 2. Multiple Choice
Convert to vertex form.y=3(x+1)2 - 8y=3(x-1) 2 - 8y=3(x+2)2 - 8y=3(x-2)2 - 8 - 3. Multiple ChoiceConvert to vertex form.y=4(x+4)2 - 62y=4(x-4)2 - 62y=4(x-8)2 - 62y=4(x+8)2 - 62
- 4. Multiple ChoiceConvert to vertex form.y=1/2(x-4)2 - 29y=1/2(x+4)2 - 29y=1/2(x+8)2 - 29y=1/2(x-8)2 - 29
- 5. Multiple ChoiceConvert to vertex form.y=-2(x+12)2 +77y=-2(x-12)2 +77y=-2(x-6)2 +77y=-2(x+6)2 +77
- 6. Multiple ChoiceConvert to vertex form.y=-(x-5)2 + 21y=-(x+5)2 + 21y=-(x+10)2 + 21y=-(x-10)2 + 21
- 7. Multiple ChoiceConvert to vertex form.y=1/3(x+3)2 - 29y=1/3(x-3)2 - 29y=1/3(x-9)2 - 29y=1/3(x+9)2 - 29
