## Homework Statement

A given surface contains all points G such that the distance from G to the plane z=4 is double the distance from point G to the pt. (2, -3, 1). Find eqn for the surface.

## Homework Equations

I thought the distance formula for a point to a plane would help, but I can tell that the equation is going to have to be that of a parabola.

## The Attempt at a Solution

I've made at least 5 unsuccessful attempts, and have NO idea where to go from here.
