The function f(x,y)=X2+Y2 has a single global minimum and is relatively easy to minimize. True False The point (x1,x2)=(4,3) is feasible for the constraint 3x1+5x240. True False [-/1 Points] CAMMIMS16 7.TB.008. Suppose each xi is a 01 variable representing whether or not project / is selected. The constraint x1+x2+x3+x42 means that two out of the first four projects must be selected. True False
