After taking a dose of medication, the amount of medicine remaining in a person's bloodstream, in milligrams, after xx hours can be modeled by the function f(x)=50(0.84)^{x}.f(x)=50(0.84) x
. Find and interpret the given function values and determine an appropriate domain for the function.
Round your answers to the nearest hundredth.

f(-2)=f(−2)=
, meaning
hours after taking the dose, there are
milligrams of medicine remaining in the person's bloodstream. This interpretation
in the context of the problem.
f(48)=f(48)=
, meaning
hours after taking the dose, there are
milligrams of medicine remaining in the person's bloodstream. This interpretation
in the context of the problem.
f(10.5)=f(10.5)=
, meaning
hours after taking the dose, there are
milligrams of medicine remaining in the person's bloodstream. This interpretation
in the context of the problem.
Based on the observations above, it is clear that an appropriate domain for the function is
.
