The standard form of a parabola:
given:
height is (which is value of the vertex)
width is
if we place the origin in the midpoint, then we have from each side of the origin
than, the vertex is at (,) and -intercepts are at (,) and (,)
....plug in ,
plug in ,
....solve for
....eq.1
plug in ,
....solve for
....eq.2
from eq.1 and eq.2 we have
go to
....eq.2, substitute
your equation is:
The factored form of a parabola:
, where and are the x-intercepts of the parabola
substitute x-intercepts
