Translate the following in words. Identify whether it is true or false. Justify your answers. ∃? ∈ ℝ, ∀? ∈ ℝ, ? = ?2.
Decide whether each of the following statements makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning.
Determine whether each of the following statements are true or false. If true, please explain why. If false, explain why or give a counterexample (whichever is appropriate). Recall that a counterexample is a specific example which shows that a statement is false. So, if I said, "All numbers are even", you would say this statement is false and remark that "3" is a counterexample. No points will be award for a correct answer without a correct explanation/counterexample for questions 1-5. For questions 6-10, no explanation is required. I have put a (C) at the end of each question which requires a counterexample if the statement is false.
