the axis of symmetry is midway between the zeros ___ x = 3

the vertex is on the axis of symmetry and is the minimum point ___ (3,-12)

the vertex form of the quadratic is ___ y = a(x - h)^2 + k , vertex at (h,k)

in this case ___ y = a(x - 3)^2 - 12

plug in the given point to find the value of "a" ___ 15 = a(6 - 3)^2 - 12 ___ 27 = 9a ___ a = 3

the relation is ___ y = 3(x - 3)^2 - 12
