1. Let TD denote a decision-adequate test set for the function in Exercise 8.13. Show that there exists a TD that fails to distinguish the abs mutant in part (c).

2. Let PJ denote a Java method corresponding to function xRaisedToy in Exercise 8.13. Which Java mutation operators will generate a non-zero number of mutants for PJ given that no other part of the program containing PJ is to be mutated ?
