Homework Help: Limit explanation

  1. Mar 9, 2015 #1
    img.jpg 1. The problem statement, all variables and given/known data

    See attached image.

    2. Relevant equations

    Left- and right-handed limits.

    3. The attempt at a solution

    I know lt (t -> 12-) f = 150 mg and lt (t -> 12+) f = 300 mg, but I don't know how to explain these numbers. I'm assuming that measurements are taken and that this graph is from these measurements. But then why can't we say f(0) = 150 mg? Does this mean that a measurement is taken "a short time after" the drug is given? Thanks for any help.

    Don't you mean f(12)?
    It seems that a measurement is made right at t = 12.

    Now that I can see the image, it looks like measurements are made just after 4, 8, 12, and 16 hours.
