- 1. Multiple Choice
Determine the vertex of the parabola y=5(x-2)2–7
(5, -7)
(-2, -7)
(2, -7)
(-7, -2)
- 2. Multiple Choice
What is the axis of symmetry of the function
y = (x + 5)2 - 12
x = 5
x = -5
x = -12
x = 12
- 3. Multiple ChoiceConvert the equation y= x2-2x-5 into vertex form.y= (x-1)2-6y= -(x-1)2-6y= (x+1)2-6y= -(x+6)2-1
- 4. Multiple Choice
The axis of symmetry for the quadratic function
f(x) = y=2(x-6)2 - 9 is wriiten as
x = -9
x = 9
x = -6
x = 6
- 5. Multiple Choice
Convert to vertex form. f(x) = 4x2 - 32x +2
y=4(x+4)2 - 62
y=4(x-4)2 - 62
y=4(x-8)2 - 62
y=4(x+8)2 - 62
- 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 Choice
Convert to vertex form. y = -2x2 + 24x + 5
y=-2(x+12)2 + 77
y=-2(x-12)2 + 77
y=-2(x-6)2 + 77
y=-2(x+6)2 + 77
- 8. Multiple ChoiceWhat is the vertex?
f(x) = -x2 - 4x + 12.(-2, 16)(2, 0)(2, 4)(-2, 4) - Answer choicesTagsAnswer choicesTags
