- Homework Statement
- Kindly see attached diagram.

- Relevant Equations
- 3d graphs

We are told that ##(x-4)(z-2)=0## The ##0## refers to what variable? The ##z=2## i think the sketch on diagram may be misleading (not to scale). Why have the ##x## crossing the axis on negative side and same applies to ##z##...

To put this into context, we may have ##(x,y,z)=(4,y,z)## where ##y## and ##z## may take any values and ##(x,y,z)=(x,y,2)## where ##x## and ##y## may take any values.
