You can put this solution on YOUR website! Find the vertex, focus, and directrix of the parabola. x^2=2y
**
Standard form of an equation for a parabola that opens upwards: (x-h)^2=4p(y-k), with (h,k) being the coordinates of the vertex
..
For given equation, x^2=2y
(h,k)=(0,0)
vertex: (0,0)
4p=2
p=1/2
focus: (0,1/2)
directrix: y=-1/2
