If A is m times n matrix then the eigen values of AT A can n

If A is m times n matrix, then the eigen values of A^T A can not be negative. The following L.P.P has an unbounded feasible region. min z = x - y subject to 4x - 3y greaterthanorequalto 0 x + y lessthanorequalto 10 x greaterthanorequalto 0, y greaterthanorequalto 0. No L.P.P with an unbounded feasible region has a solution.

Solution

d. True

e. True

f. False, minimization problem with unbounded feasible region can also have a solution
