Suppose you want to refute the statement: There are some natural numbers a, b, and c where a | b and b | c but a does not divide c. Which of the following would be an appropriate strategy for you to employ? Group of answer choices Show specific values for a, b, and c where a | b and b | c and a | c. Show specific values for a, b, and c where a does not divide b and b does not divide c, but a | c. Show for any generic choices of a, b, and c that if a | b and b | c then a | c. Show for any generic choices of a, b, and c if a does not divide b and b does not divide c then a does not divide c.
6. Fill in the blank with "all", "no", or “some" to make the following statements true. Note that "some" means one or more instances, but not all. • If your answer is "all", then give a brief explanation as to why. If your answer is "no", then give an example and a brief explanation as to why. • If your answer is "some", then give two specific examples that illustrate why your answer it not "all" or "no". Be sure to explain your two examples. An example must include either a graph or a specific function. (a) For (a, b). functions f, if f"(x) > 0 on the interval (a, b), then f'(x) < 0 on the interval (b) For functions f, if f(x) is a polynomial, then it is differentiable for all x. (c) For f(x) at exactly one point. functions f, the tangent line to f(x) at x = a will intersect the graph of In mathematics, we consider a statement to be false if we can find any examples where the statement is not true. We refer to these examples as counterexamples. Note that a counterexample is an example…
