this is the graph. do i just find four random points now that lay on it?

Good!

Yes.

would points like these work
(0,2,4)
(0, sqrt(3), 3)
(0, sqrt(2), 2)
(0,-1,1)

Yep!
But wouldn't it be nice to include some point with $x\ne0$?[/color]

i tried that but i wasnt sure if it was on the graph because i noticed that it was longer in the y direction and i couldn't afford to make any mistakes (test question) (Giggle) (didnt know you could edit latex as a global moderator. in that case you probably want to go edit my interval for the length of an arc thread (Rofl))

Ah well. As long as you're afraid to make mistakes with questions like these, you've come to the right place! (Evilgrin)

Nope. No need, since I can read it without reformatting it. (Lipssealed)
