Concept explainers
A patient receives a drug. This situation gives rise to a drug function for which the input is the time elapsed since the drug was administered and the output is the amount of the drug in the patient’s blood (in milligrams per milliliter of blood). The graph of this drug function is shown in Figure 9.60 .
Figure 9.60 The graph of a Drug function
- Give the approximate coordinates of point A, and discuss the significance of this point in terms of the scenario about the patient and the drug.
- Give the approximate coordinates of point B, and discuss the significance of this point in terms of the scenario about the patient and the drug.
- Overall, discuss what the graph tells you about the patient and the drug.
