This is an equation of parabola.

Standard equation of a parabola with Y axis symmetry is given by

#### Explanation:

Simply rearranging the terms from y=

you can get the standard equation of a parabola

as

This is a downward opening parabola with negative Y axis as the axis of symmetry.

From the standard equation the co-ordinates of focus are (h,k+p).

So the focus of this parabola is (0,-1).

the vertex is (h,k) => vertex is (0,0)
