Refer to the figures on the right for the following questions. If you are asked to identify a surface, use the
Roman numeral to identify the surface.
(a) Rewrite the equation in standard form,
then identify which surface could be represented
by the equation x²+4z² = 16-4y².
(b) Rewrite the equation in standard form,
then identify which surface could be represented
by the equation y-3x²=-2z².
(c) Write a possible equation to describe surface II.
