Re: ???
The first part happens (if i understand you correctly) because you are
trying to graph something similar to a circle (i.e. it comes back around)
and would therefore have two y-values for one or more x-values, and is then
by definituion, not a function. the other part may be happening because
you are using one equals sign instead of two. Hope this helps
