Need help with my writing homework on Modelling the Amount of a Drug in the Bloodstream. Write a 1250 word paper answering; Finally, graphs will be made and discussed for. what would happen over the next week if no further does were taken and what would happen if doses would continue to be taken every 6 hours.
From the above figure 1, it is evident that the amount of drug decreases as time passes. By seeing the graph, it is also evident that the rate at which the drug decreases in the bloodstream is proportionate to the amount remaining. Therefore, the data follows a certain pattern that is of type of an exponential decay graph.   
From the given values, the initial amount at time = 0 is 10 µg. Therefore, the value of A will be 10. Since the data represent approximate values, therefore the exact value of k cannot be determined for the pattern of the amount remaining in the bloodstream over a period. However, an approximate value of k can be determined for each data point, and then the average value will be taken from these determined values of k. The value of k for single data points can be determined by below-mentioned example:
From the above graph (figure2) of model function, it is evident that the model function follows the same pattern as shown in the given graph of ‘amount of a drug in a bloodstream’. At some points, given data points slightly differ from the graph function. However, it is evident that the model function represents the exact pattern for drugs remained over a period in the bloodstream.
The model function can be used for determining the approximate value of drugs remained at any given time. Therefore, it is evident that the model function is suitable for the given graph of ‘Amount of a Drug in the Bloodstream”.
If a patient is instructed to take 10 µg drug after every six hours, then the initial amount of drug remained in the bloodstream will be added to the new dose of 10 µg. From the given graph (figure 1), it is evident that after six-hour the amount of drug remained is 3.7 µg. .
