Find the absolute maximum and minimum values of the following function on the given interval. If there are multiple points in a single category list the points in increasing order in $x$ value and enter N in any blank that you don't need to use.
$$f(x)= 3 e^{7 x^3 - 7 x} \qquad -1 \leq x \leq 0$$

Absolute maxima
$x =$      $y =$
$x =$      $y =$
$x =$      $y =$

Absolute minima
