) Find all local maxima, local minima, and saddle points of each function. Enter each point as an ordered triple, e.g., "(1,5,10)". If there is more than one point of a given type, enter a comma- separated list of ordered triples. If there are no points of a given type, enter "none". f(r, y) = 9x³ + 6xy+6y³ Local maxima are none Local minima are none Saddle points are none
