The function f has a domain of {1, 3, 5, 7} and a range of {2, 4, 6}.
could f be represented by {(1,2), (3,4), (5,6), (7,2)}?
justify your answer.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
