Identify the properties of the given quadratic. y = −3x2 + 6x + 17 a: b: c: Axis of symmetry:

y = ax2 + cAxis of symmetry: y = 0y = –c✔ x = 0x = a

Vertex: (0, ⇒ -12)

What is the distance from the given zero to the line of symmetry?

x f(x) = −x2 + x + 6 −2 a −1 4 0 b 1 6 2 c a = b = c =

Vertex: (, )

Vertex: (0, )

What is the other zero of the quadratic function?

a = b = c =

x f(x) = −x2 + x + 6 −2 a −1 4 0 b 1 6 2 c a = b = c =

y = –3x2 – 12Axis of symmetry: x = 12y = –12y= –3✔ x = 0

a = b = c =

The larger zero is .
