A linear function f(x,y)=ax+by+c has no critical points. Therefore, the global minimum and maximum values of f(x,y) on a closed and bounded domain must occur on the boundary of the domain. Furthermore, it can be easily seen that if the domain is a polygon, as in the figure, then the global minimum and maximum values of f must occur at a vertex of the polygon. Find the global minimum and maximum values of f(x,y) on the specified polygon. f(x,y)=6y?4x+5 (Give your answers as a whole numbers.) global minimum: global maximum:
