What is being asked?

jasbe · Answer

@sunnnystrong       it's just asking me to solve for equations.

supercalifragalisticexspeaalli · Answer

ok

sunnnystrong · Answer

I think you are just supposed to find which set of numbers belongs to each equation. For example, if you input the first set (-1,2,1) into the equation where (x,y,z) than the statement is true.
The first set belongs to the first equation.

jasbe · Answer

@sunnnystrong no the answers are grouped as one if that makes since its not asking for a answer to each equation.

sunnnystrong · Answer

Well, if you check the first set with my theory it is true for all functions versus the other sets are not true.

I'm not sure what is being asked.
