Find the critical points of f(x)=-12x4+4x2-3 and apply the Second Derivative Test (if possible) to determine whetherDetermine the exact values at which inflection points occur, if any, of the function f.
f(x)=x/e8x
Give your answer as a comma-separated list. If the function does not have any inflection points, enter DNE.
each of them corresponds to a local minimum or maximum.
(Use symbolic notation and fractions where needed. Give your answer in the form of a comma separated list. Enter DNE if there
are no critical points.)
