cone
The 3D shape with one face and one vertex is a cone. A cone has a circular base that serves as its singular face, while the point at the top where all the lines from the base converge is the vertex. It can also be considered an apex, where the shape tapers to a single point.
It is called a cone.
A right cylindrical cone has a circle for a base and one vertex. a diagram is shown on unitmath.com
The 3-D shape with one edge, two faces, and one vertex is a cone. It has a circular base (one face) and a curved surface that tapers to a point (the vertex). The edge is the circular boundary of the base.
The shape with 1 vertex and 2 faces is a cone. A cone has a circular base as one face and a curved surface that narrows to a single point, known as the apex or vertex. Therefore, it can be described as having one vertex and two distinct surfaces.

One possible answer is an infinite cone. Spheres have one face but no vertex. No physical 3-D shape can have a vertex without having more than one face (a real cone typically has two: side and bottom).
