Answer:
A rectangle is any four sided shape that has four right angles; Therefore, since a square is a four sided shape that has four right angles and congruent (equal) sides, it always has to be a rectangle. However a rectangle does not always have congruent sides, so it is not necessarily a square.

PART A
The equation of the parabola in vertex form is given by the formula,

where

is the vertex of the parabola.
We substitute these values to obtain,

The point, (3,6) lies on the parabola.
It must therefore satisfy its equation.




Hence the equation of the parabola in vertex form is

PART B
To obtain the equation of the parabola in standard form, we expand the vertex form of the equation.

This implies that

We expand to obtain,

This will give us,


This equation is now in the form,

where

This is the standard form
