how to do a parabola in geogebra 3D

[tender jasper]

Does anyone know about Geogebra 3D and can give me the formula or the command to enter a parabola?
So it looks like the picture below

Paraboloid or parabola?

[tender jasper]

Just a parabola

A parabola is a system of equations between a paraboloid and a plane. cutting them creates a parabola

[pale cave]

z=x^2+y^2

[sullen hinge]

Paraboloid is Z/c=x²/a²+y²/b² and plane can be Z=2

Depends which parabola you want

Sorry not Z=2

Because it will be circle

But y= 2 or X=1 depends

And form of them will be Z=x²/a²+2²/b² or Z=1²/a²+y²/b²

It's ok ?

What does "/" and "x,a,b" stand for?
