(a) Everyone who is majoring in math has a friend who needs help with their homework.
(b) Everyone likes someone, but no one likes everyone.
(c) There exists a non-zero real number a such that a+ x = x, for every real number x.
(d) Every non-constant polynomial p(x) is such that its derivative is not zero.
(e) For every positive number M, there exists a positive number N such that f(x) > M whenever x > N.

Expert Solution
Step 1

(a) x is a person

p(x) = x is majoring in math

q(x) = friend who needs help with their homework

The given statement is x p(x) q(x)

Negation of this statement would be x p(x)~q(x).

That is,

There is a person who is majoring in math and has a friend who doesn't need help with their homework.
