What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: w -> Q_3(f_4). forall z: T_4(z) -> Q_3(z). ~T_4(f_4). forall z: Q_3(z) <-> T_4(z).
forall z: Q_3(z) -> T_4(z) can be inferred via the universal biconditional elimination rule. forall z: T_4(z) -> Q_3(z) can be inferred via the universal biconditional elimination rule.
