Given: x + 2 < -5.
choose the solution set.
{xixer, x< -7}
{xixer, x< -3)
{xixer, x< 3)
© {xixer, x< 7)

We have

.

We can simplify this expression to

.

Which can be written as

or

.

Hope this helps.

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
