Which estimation technique will yield a solution that is closest to the actual product of (–21.06)(–30.45)? front-end estimation
rounding to the nearest tenth
rounding to the nearest whole number
compatible numbers

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
