Step-by-step explanation:

(–2)2 + (–4)2 + (18 – 23) = -4-8-5= -17

it is a reproduction.

step-by-step explanation:

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
