The fn f$($x$)=2$x$^6-12$x$^4$ The $x-$intercepts occur at $x=$

NOTE: If there are more than one, separate your answers by a comma.

There a y$-$intercept at $y=$

To analyze hite shape of the graph of $f$ it helps to separate the domain into disjoint open intervals

whose endpoints

$f{f}^{\text{'}}f{f}^{\text{'}}{f}^{\text{'}}{f}^{\text{'}\text{'}}A=$

$B=$

$C=$

$D=$

$E=A$

are critical points $offor{f}^{\text{'}}.$ Inside each interval there are $no$ critical points $offor{f}^{\text{'}},so{f}^{\text{'}}$ and $f^{\text{'}\text{'}}$ cannot

$A=$

$B=$

$C=$

$D=$

$E=$
