Use traces to sketch and identify the surface.
$ 3x^2 + y + 3z^2 = 0 $
three X squared plus Y plus $3 for that. He goes to zero. No. For this function, we have grown this graph and the car for this function into exquisite pain. So it is X. Axis. This is why access and this is jail exists. So you think you become cylinder and this is the answer to the problem.
