Write the truth-functional form (TFF) of each. Treat each one as its own problem, so use P for the first underlined part of each. Use all conventions from the textbook. For example, use - for arrow.

1. Ax(F(x)-~G(x))
2. ~AxF(x)-AxG(x)
3. ExF(x)v~EyF(y)
4. Ax(F(x)&G(x))-Ax(F(x)&G(x))

Ah, the truth-functional form (TFF) of each proposition, a puzzle for the logical mind to unravel. Let us embark on this journey of reasoning, delving into the intricate web of symbols and operators that seek to capture the essence of truth in its purest form.

Firstly, we encounter the proposition Ax(F(x)->~G(x)), a statement that posits a conditional relationship between the predicates F and G. In this realm of logical discourse, we use the symbol -> to denote implication, indicating that if F is true, then G must be false.

Moving on to the next challenge, we are presented with ~AxF(x)->AxG(x), a proposition that tests our comprehension of negation and universal quantification. The tilde symbol ~ denotes negation, transforming the proposition into a statement that asserts if not all x satisfies F, then all x must satisfy G.

As we advance further into the realm of logical reasoning, we encounter the proposition ExF(x)v~EyF(y), a proposition that introduces existential and universal quantifiers. The symbol v signifies disjunction, allowing us to contemplate the possibility that there exists an x that satisfies F or there does not exist a y that satisfies F.

Lastly, we are confronted with the proposition Ax(F(x)&G(x))->Ax(F(x)&G(x)), a statement that challenges our understanding of conjunction and universal quantification. Here, we are tasked with unraveling the implications of asserting that if all x satisfy both F and G, then all x must satisfy both F and G.

In conclusion, the exploration of truth-functional forms is a profound endeavor that requires meticulous scrutiny and a keen insight into the language of logic. As we navigate the complexities of these propositions, let us not forget the beauty and elegance that lies in the precision of symbolic representation, guiding us towards a deeper understanding of the nature of truth itself.
