Consider the formula A : ∃x.[(∀y.P(x, y) → R(x)) → ¬∃z.Q(x, z)] (a) Find a formula equivalent to A that only has negation symbols in front of basic formulas. (b) Give an example of an interpretation where A is true. The domain should be the set N. (c) Give an example of an interpretation where A is false. The domain should be the set N.

Suppose x,y ∈ R and assume that x < y. Show that for all z ∈ (x,y), there exists α ∈ (0,1) so that αx+(1−α)y = z. Now, also prove that a set X ⊆ R is convex if and only if the set X satisfies the property that for all x,y ∈ X, with x < y, for all z ∈ (x,y), z ∈ X.
