1
What is the formula to find the axis of symmetry?
x = -a/2b
x = b/2a
x = -b/a
x = -b/2a
2
What is the shape of a quadratic function graph?
axis of symmetry
line
vertex
parabola
3
Where is the axis of symmetry?
Through the vertex.
Underneath the parabola.
Through the center of the graph.
There is no axis of symmetry.
4
What is the axis of symmetry for y = 8(x - 7)
2
+ 3?
x = 7
x = -7
x = 8
x = 3
5
What is the vertex of the given graph?
There is no vertex.
x = 2
(2,1)
x = 1 and 3
6
Which is the formula for a quadratic in Vertex Form?
y = a(x - h)2 + k
y = a(x + h)2 + k
y = ax2 + bx + c
y = a(x + h)2 - k
7
Why does the graph of a quadratic equation, y = -ax
2
+ bx + c, point downwards?
Because there are 3 terms
All quadratics point downwards.
Because a is negative
I don't know.
8
What is the axis of symmetry of y = 3(x + 1)
2?
x = 0
x = 3
x = -1
x = 1
9
What is the axis of symmetry for the given graph?
There is no axis of symmetry.
x = 2
x = 1 and 3
(1, 2)
10
What is the vertex of y = 2(x - 4)
2
+ 3?
(4, 3)
(-4, 3)
(4, -3)
(-4, -3)
11
What is the standard form for a quadratic equation?
y = mx + b
y = x2
y = a(x - h)2 + k
y = ax2 + bx + c
12
What is the axis of symmetry & vertex of y = 3(x + 1)
2
- 7?
x = 1; Vertex (1, -7)
x = 3; Vertex (-1, -7)
x = -1; Vertex (-1, 7)
x = -1; Vertex (-1, -7)
