Given the predicates P(x) = (x^2 > 0) and Q(x) = (x ≠ 0), prove that ∀x(P(x) → Q(x)).
💡 Hint: Examine the conditions under which P will lead to Q. Just analyze both predicates together.
Create an example where universal quantification fails in certain domains while holding true in others.
💡 Hint: Try out edge cases when including boundary values.
