What is the domain/range of the z-axis called?

[Anonymous No.4409178]

Anyone? I've been search for a while now and cant find anything

[Anonymous No.4409184]

Depth.

That's a total guess.

[Anonymous No.4409186]

Domain is the independent variables, range is the dependent variable.

No, but I'm talking about a 3d plane, (x,y,z)

[Anonymous No.4409197]

Well whats is the domain/range of the x and y axes called? I don't get what you mean.

Domain and range. What is the name for the limits of z of a function on the yz-plane?

I'm aware you are dealing with a 3D coordinate system. The statement still applies. Domain is independent variables and range is dependent variables.

I'm not modeling a function, I'm describing a plane defined by 3D vectors.

Domain and range are not the names of the axes. Domain is what the indepandant variable can be; range is what the dependant variable can be; and traditionally x is the independent and y the dependent in a two-variable.

In the context of an equation of three variables, it all depends of what is independant and what is dependant. Normally, x and y would be independant and therefore rescrited to a certain domain and z dependent and therefore restricted to a certain range.

However it is equally possible to define both y and z in terms of x which would make x the domain and both y and z the range.

>>4409232
So how would you define in terms of domain and range, the limits xER | -2 <= x <= 0, y = 4, zER | -7 <= z <= 0

In this format:

Domain: {xER | xER | -2 <= x <= 0}
Range: {y = 4}

Woops, extra xER
