Homework Help Overview

The discussion revolves around the concept of two-variable graphs, exploring definitions and contexts in which they are used, particularly in relation to functions of one or two variables and their graphical representations.

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants are attempting to clarify the definition of a two-variable graph, questioning whether it refers to functions of one variable or two variables. Some are exploring the context of statistics versus coordinate geometry.

Discussion Status

There is an ongoing exploration of different interpretations of what constitutes a two-variable graph, with some participants providing clarifications and examples. The discussion includes references to specific types of graphs, such as level set curves and 3D graphs, but lacks a definitive consensus on terminology.

Contextual Notes

Participants express uncertainty about the terminology used and its implications in different mathematical contexts, such as statistics and coordinate geometry. There is mention of a project requirement related to creating a two-variable graph, indicating a practical application of the discussion.

hi, I just need to what is a two-variable graph. Any help would be appreciated.

Thanks

That is not a standard terminology. It could mean either the graph of a function of one variable: y= f(x) in a cartesian coordinate system with one x-axis and one y-axis or (perhaps more likely what you mean) a function of two variables: z= f(x,y). To graph that you need three axes, x, y, z with the z-value (height of a surface above the xy-plane) given by f(x,y).
 
Is this a two-variable graph?

Also, could you bumb your explanation down for me since I'm a dumbask?
 
Are you talking about statistics or co-ordinate geometry. Your terminlogy does not make this thing atleast specific?
 
Raza:
Those on your image are called level set curves; each is characterized by a constant value of R^2
 
I have a project which states me to make a two-variable graph. This is for Data Management which is study for statistics. Are "Grade-10" and "Grade-12" variables?
 
So a 3D graph is a two-variable graph?
 
I believe that would be one way to put it!
