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(x,y) = 1-√√1x² + 7y² Local maxima are none Local minima are none Saddle points are none
