Nount of medication
lesson 22-2 practice
20. the amount of medication in a patient's bloodstream decreases
exponentially from the time the medication is administered.
particular medication, a function that gives the amount of medi
in a patient's bloodstream t hours after taking a 100 mg dose is
a(t)=100(2). use this function to find the amount of medicatie
remaining after 2 hours.
21. make a table of values and graph each function.
a. h(x) = 2."
b. 1(x) = 34
c. m(x)=(1
d. p(x)=(1)
22. which of the functions in item 21 represent exponential growth? whis
of the functions represent exponential decay? explain using your tabia
of values and graph.
23. reason abstractly. how can you identify which of the functions
represent growth or decay by looking at the function?
24. express regularity in repeated reasoning. write an exponential
function and identify its constant factor.
