Which equation represents the transformed function below? = parent function; y=logx = transformed function options y=logx+5 y=logx-5 y=log(x+5) y=log(x-5)

X+ y = 5 ; x - y =3 solve using linear combination

Find the domain of the following expression: 1/(√x)-2

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
