Example 17 - Find all points of local maxima and local minima

Finding Local Maxima of a Function Given the Graph | Algebra | Study.com

SOLVED: 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) = 6x^2 4xy 3y^2 - Tx Ty - 6Local maxima are Local minima are Saddle points are f(x,y) = 8x^2 TxyLocal maxima are Local minima are Saddle points are f(x,y) = 4 - 2x^2 8y^2Local maxima are Local
