answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
