What does the equation xyz=0 represent in the region of R^3?

Click For Summary
SUMMARY

The equation xyz=0 represents a specific region in R^3, which includes the entire coordinate planes: the xy-plane, xz-plane, and yz-plane. This is because the product of the coordinates x, y, and z equals zero when at least one of the coordinates is zero. Therefore, any point where either x=0, y=0, or z=0 satisfies the equation, leading to an infinite set of points along these planes, including the origin (0,0,0).

xyz=0

The Attempt at a Solution



I'm not really sure how to look at the equation. I would think its just the point (0,0,0). Can someone explain if this is wrong.

Um, (1,0,0) also satisfies the equation. Describe the other points that do.
 
Surely you know "if AB= 0 then either A= 0 or B= 0 or both".
