Suppose that the amount of energy (x, y, z) emanating from a source at (0, 0, 0) is inversely proportional to one more than the square of the distance from the origin measured only in the xy-plane, and is directly proportional to the height above the xy-plane. Assume that all of the constants of proportionality are equal to 1. -What is an equation for the energy as a function of x, y, and z? -Where is there no energy at all? -Please sketch the level surface ɛ(x, y, z) = 1
