Um...does anyone know how to sketch x = y^3 - 16y?

if you have a TI graphing calculator, go to parametric mode and graph

$X_{1T} = T^3 - 16T$
$Y_{1T} = T$

the following window settings give a good look at the graph ...

$T_{min} = -10$
$T_{max} = 10$
$T_{step} = 0.1$
$X_{min} = -30$
$X_{max} = 30$
$Y_{min} = -8$
$Y_{max} = 8$
