Question
Let \( E \) be the tetrahedron with vertices: \( (0, 0, 0), (3, 2, 0), (0, 3, 0), (0, 0, 2) \).

\( E \) is bounded by four planes: \( z = 0 \), \( x = 0 \), \( -2x + 3y = 0 \), \( 2x + 6y + 9z = 18 \).

### Diagram Description
There is a 3D coordinate system diagram showing the tetrahedron. The axes are labeled \( x \), \( y \), and \( z \). The vertices are shown at the specified coordinates. The edges and faces of the tetrahedron are drawn connecting the vertices.

(a) \( V(E) = \) [Volume of the tetrahedron space - placeholder for answer]

(b) Average of \( f(x, y, z) = x + 2y - z \) on \( E \) is: [Placeholder for computed average value]
