    Let R be the feasible region (convex polygon) for a linear programming problem and let \[Z=ax+by\] be objective function. When Z has an optimal value (Maximum or minimum), where the variables x and y are subject to constraints described by linear inequalities, this optimal value must occur at a corner point (vertex) of the feasible region.
    Based on the above information, answer the following questions:
    Objective function of a L.P.P. is

    A) a constant

    B) a function to be optimized

    C) a relation between the variables

    D) None of these.

    Correct Answer: B

    Solution :

    Objective function is a linear function (involve variable) whose maximum or minimum value is to be found.
