Quizplus · Accepted Answer

The Answer of Classify the following surface as ellipsoid, elliptical paraboloid, hyperbolic paraboloid, hyperboloid of one sheet, hyperboloid of two sheets, or cone. $- 9 x ^ { 2 } - 4 y ^ { 2 } + z ^ { 2 } = 9$

Classify the Following Surface as Ellipsoid, Elliptical Paraboloid, Hyperbolic Paraboloid −9x2−4y2+z2=9- 9 x ^ { 2 } - 4 y ^ { 2 } + z ^ { 2 } = 9−9x2−4y2+z2=9

Classify the Following Surface as Ellipsoid, Elliptical Paraboloid, Hyperbolic Paraboloid $- 9 x ^ { 2 } - 4 y ^ { 2 } + z ^ { 2 } = 9$
