Question: What is the local maximum and minimum values and saddle point(s) of the function? f ( x , y ) = x 3 - 27

What is the local maximum and minimum values and saddle point(s) of the function?

f(x,y) =x3-27xy+27y3

maximum

f(,) =(smallerxvalue)

f(,) =(largerxvalue)

minimum

f(,) =(smallerxvalue)

f(,) =(largerxvalue)

saddle points

(,) (smallestxvalue)

(,) (largestxvalue)
