The equation c(t)=4t/t^2+2 describes the concentration of a medicine in the bloodstream after a fixed number of hours. the concentration is measured in parts per million. identify the graph of this rational function.

Let

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

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

we have

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
