How do I correlate the dimensional equatorial vertices of a dodecahydrophoric cubeangle?

i dunno why but this actually made me laugh pretty hard.
my old geometry teacher had a chart with a bunch of the polyhedrons and we would just ask her questions about them instead of whatever the actual geometry was.

What the heck?

fine,
if Given f(x) = e(^x2 - x) find the the intervals of increase and decrease of f, the values of x for which f has a local extremum, and the intervals of concavity and inflection points.
thanks
