Question

Which set gives the complete non-negative restrictions for the profit-maximization formulation?

पर्याय

• \[x\geq 0,\ y\leq 0\]

• \[x\geq 0,\ y\geq 0\]

• \[x\leq 0,\ y\leq 0\]

• \[x+y\geq 0\]

Answer 1

Both decision variables must be non-negative. Therefore, the required restrictions are \[x\geq 0,\ y\geq 0\], not merely a restriction on their sum.
