c) Describe the set of all 7. For a function f:A → B, the statement "f is surjective" is defined by the quantifier expression "(VvEB)(3uEA) (f(u) = v)". Consider the statement "(3 u E A) (VvE B) (f(u) = v)", in which the order of the quantified variables has been reversed. a) In intuitive terms, what does this new statement mean? b) Are there functions for which this new statement is true? If so, are they all surjective? c) Are there surjective functions f for which this new statement is false? nos" quantifier which is used to abbrevi-
