See attachment for the question.

----------------

∀x ∈ D, if P(x) then Q(x). this means ∀x P(x) -> Q(x).

all you have to do is find a value for x

∀x this means for ALL x right

so you can choose ANY element

but for the E its only things in the domain

so all you have to do is choose an x that's not in E's domain

and then you can say therefore its not logically equivalent.

I think am wrong.

----------------

Please help me out with this problem.

thank you in advance.
