(1 point) Let \( f ( x ) = e ^ { - 6 x ^ { 2 } } \)
Then \( f ( x ) \) has a relative minimum at
\( x = \) a relative maximum at
\( x = \) and inflection points at
\( x = \)
and at
\( x = \) Write DNE if any of the above do not exist. Write the inflection points (if any) in numerical order, smallest first.
