consider the following proposition

Question 14 Consider the following proposition: For any predicates P(x) and Q(x) over a domain D, the negation of the statement 3x E D, P(x) A Q(x) is the statement VVE D, P(x) ? "Q(x). We can use this truth to write the negation of the following statement: There exist integers a and d such that a and d are negative and a/d 1+ d/a. Which one of the alternatives provides the negation of this statement? 1+ d/a. 1. There exist integers a and d such that a and d are positive and a/d 2. For all integers a and d, if a and d are positive then a/d 1 + d/a. 3. For all integers a and d, if a and d are negative then ald # 1 + d/a. 4. For all integers a and d, a and d are positive and a/d 1 + d/a. 30
