Expert Solution
Step 1

Given Equation is :

                                 y=x24+z28y=2x2+z282x2+z2=8y

 

Since,

           This equation is of second degree

           Hence, it represents the quadric surfaces and the equation of the paraboloid .

 

 

Step 2

Quadric surfaces are those surfaces with the second degree equation in three variables.

Hence,

                             y=x24+z28

 

This is the paraboloid with vertex at the origin (0, 0) and opening  along the y-axis.

 

Therefore,

             The name of the surface is  Quadric(Paraboloid).
