Given: f(x) = 3x – 7,
g(x) = 2x – 3x +1,
h(x) = 4x +1, k(2) = -x+3
Find: (k - g) (x)

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
