After taking a medication its concentration in the bloodstream behaves as shown in the graph 650t/(t^3+200), where the x values are hours since first taking the medication and y is the concentration of the medication (mg/cc) in the blood stream after the given number of hours. The time x = 0 occurs at Monday 8:00 a.m.
Identify the sources of error and explain whether or not we can we compensate for them.
No graph shown; 650t/(t^3+200) doesn't mean anything to me. I don't see any x values or y values.
