Please see below.

Explanation:

.

The general form of a parabola equation if it is an up or down parabola is:

y=ax^2+bx+c

If it is a sideways parabola it is:

x=ay^2+by+c

The vertex form of an up or down parabola is:

y=a(x-h)^2+k

The vertex form for a sideways parabola is:

x=a(y-k)^2+h

It is important to remember that h always stays with x and k always stays with y.

The coordinates of the vertex of the parabola are:

vertex (h,k)

which means h and k are x and y coordinates of the vertex.

1/(4a) represents the distance between the vertex and the focus of the parabola.
