Steve,

The following rational function describes concentration in blood of a certain medicine taken once depending on time, find: A. the horizontal asymptote B. the vertical asymptote C. describe their possible meaning ( I only need help with C). f(x)=x/x^2-100

as you can see from the graph, the concentration appears to be negative until x=10. Then it explodes and then drops down.

I cannot think what the vertical asymptote can represent, unless there's some delayed-release capsule, and the asymptote is just an approximation to the sudden release of medicine. I think that's a bigus function.
Thank you
