f(x) = 2x^6 – 4x^4 -5 Use either the first derivative test or the second derivative test to find the following: (A) The average of the values of all local maxima of . Note: If there are no local maxima, enter -1000. Average of values = (B) The average of the values of all local minima of . Note: If there are no local minima, enter -1000. Average of values =
