When I plot
[itex] y = 3x^{\frac{4}{3}}-\frac{3}{32}x^{\frac{2}{3}}[/itex],
I get: https://dl.dropbox.com/u/5653705/pfgraph1.png
but I don't see any reason for the domain to be restricted to [itex] x > 0 [/itex]. There is only a cubic root, which is well defined for negative numbers ... I've tried on a few different programs & always get the same thing, can anyone explain why? Is the domain actually restricted to positive x?
Thanks in advance,
Rax
