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: ~p_3. forall x: T(x) <-> R(x). p_3 <-> T(j_1).
p_3 -> T(j_1) can be inferred via the biconditional elimination rule. T(j_1) -> p_3 can be inferred via the biconditional elimination rule. ~T(j_1) can be inferred via the biconditional elimination rule. forall x: T(x) -> R(x) can be inferred via the universal biconditional elimination rule. forall x: R(x) -> T(x) can be inferred via the universal biconditional elimination rule.
