Let a be a real number and let f be a real-valued function defined on an interval containing x = a. Consider the following conditional statement: If f is differentiable at x = a, then f is continuous at x = a. Which of the following statements have the same meaning as this conditional statement and which ones are negations of this conditional statement? Note: This is not asking which statements are true and which are false. It is asking which statements are logically equivalent to the given statement. It might be helpful to let P represent the hypothesis of the given statement, Q represent the conclusion, and then determine a symbolic representation for each statement. Instead of using truth tables, try to use already established logical equivalencies to justify your conclusions.
