Question

I already have the critical points (c ^ {- 1/3}, c ^ {1/3}) is a relative minimum, I need to locate the relative extremes of f in D1

21.T. Let f be defined on D = {(, n) € R':{ > 0, 7 > 0} to R by the formula
f(E, n) =
1
1
++ cEn.
Locate the critical points of f and determine whether they yield relative maxima,
relative minima, or saddle points. If c > 0 and we set
Di = { (, n): > 0, n > 0, + n < c},
then locate the relative extrema of f on Di.
