Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the $x-$values at which they occur.

$f(x)=2x^3-2x^2-2x+5$;$[-1,2]$

The absolute maximum value is at $x=$

$($Round to two decimal places as needed. Use a comma to separate answers as needed.$)$

The absolute minimum value is at $x=$

$($Round to two decimal places as needed. Use a comma to separate answers as needed.$)$
