Question #8f220

Answer 1

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.
