You are given an NP-Hard minimization problem PROBLEM (PROBLEM can be for example General TSP), and for any instance I, the solution of PROBLEM on I is either exactly or > c*mu where c >1 is a constant, and u is a parameter that depends on I. Then, there is no polynomial time c-approximation algorithm for PROBLEM because:
