Need help: A patient receives a 150mg injection of a drug every 4 hrs. The graph shows the amnt f(t) of he drug in the blood steam after t hours. Find lim of f(t) as t approches to 12(left) and 12(right)m and explain the significance of these onesided limits.

I believe so, at least judging by your sketch you made.

okay and what about the significance?

The significance is that the twosided limit, or the limit as x approaches 12 exists.

oh well that's much different then! The limit from the left is 150. The limit from the right is 300. The significance is that the limits from the left show the medicine in the blood left and the limit from the right shows how much medicine the patient has in the blood after another dose.

how is it 300 from the right?

Well, I'm assuming that the open circle is supposed to be directly above the shaded circle at x=12?

Exactly. If it's directly above, then you follow the graph from either side. You've got it!

The significance of these onesided limits is that they indicate a discontinuous change in the amount of drug, caused by the injection.
