Question

Translate each of the following sentences into symbolic logic, then find their negation.


(a) There exists a non-zero real number a such that a+ x = x, for every real number x.

(b) Every non-constant polynomial p(x) is such that its derivative is not zero.

(c) For every positive number M, there exists a positive number N such that f(x) > M whenever x > N.

(d) Everyone likes someone, but no one likes everyone. 

(e) Everyone who is majoring in math has a friend who needs help with his/her homework.

Expert Solution
Step 1: Step 1

We have to translate each of the sentences into symbolic logic. And, then we will find its negation.


(a) There exists a non-zero real number a such that a+x=x, for every real number x.

In symbolic logic, there exists a element of straight real numbers backslash open curly brackets 0 close curly brackets space for all x element of straight real numbers open parentheses a plus x equals x close parentheses.

It's negation is for all a element of straight real numbers backslash open curly brackets 0 close curly brackets space there exists x element of straight real numbers open parentheses a plus x not equal to x close parentheses.
