Essay

Write negations for each of the following statements:
(a) For all integers nn , if nn is prime then nn is odd.
(b) \forall real numbers xx , if x<1x < 1 then 1x>1\frac { 1 } { x } > 1 .
(c) For all integers aa and bb , if a2a ^ { 2 } divides b2b ^ { 2 } then aa divides bb .
(d) \forall real numbers xx , if x(x2)>0x ( x - 2 ) > 0 then x>2x > 2 or x<0x < 0 .
(e) \forall real numbers xx , if x(x2)0x ( x - 2 ) \leq 0 then 0x20 \leq x \leq 2 .
(f) For all real numbers xx and yy with x<yx < y , there exists an integer nn such that xnyx \leq n \leq y .
