Let

C(t)--------->the concentration of a medicine in the bloodstream

t---------> the number of hours

we have

$C(t)=4t/(t^{2}+2)$

Using a graphing tool

see the attached figure

The domain of the function is all positive real numbers------> [0,∞)

The range of the function is the interval----------> [0,1.414]

therefore

the answer in the attached figure
