You can put this solution on YOUR website!
the vertex form of a Parabola opening up(a>0) or down(a<0),
y=a%28x-h%29%5E2+%2Bk where(h,k) is the vertex
.....
V(-1/2, 0)
y=a%28x-1%2F2%29%5E2+%2B+0
y=a%28x-1%2F2%29%5E2
....three examples
y = (x-1/2)^2 (Green)
y = -(x-1/2)^2 (Blue)
y = 2(x-1/2)^2 (Purple)
