Clear[f];

f[x_] = x^(1/3);

Plot[Sign[x] Abs[f[x]], {x, -10, 10}]

However, if this graph represents the function that you want, then the function definition should be similar to

Clear[f];

f[x_] = Sign[x] Abs[x]^(1/3);

Plot[f[x], {x, -10, 10}]

=============
The above package no longer exists in Mathematica 7 and must be
downloaded.  Then to use the feature it seems there must be additional
code entered to turn off certain warnings.  It's an annoyance.  When
graphing functions such as f(x) = x^(1/3) is there a workaround to get
the full graph, -inf<x<inf?
