Homework Help Overview

The discussion revolves around the interpretation of left- and right-handed limits in the context of a graph representing drug measurements over time. Participants are trying to understand the significance of the values 150 mg and 300 mg at the point where time approaches 12 hours.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to explain the meaning of the left-hand limit (150 mg) and the right-hand limit (300 mg) as time approaches 12 hours. Questions are raised about why f(0) cannot be equated to 150 mg and whether measurements are taken immediately after the drug is administered.

Discussion Status

The discussion is ongoing, with participants exploring the implications of the limits and clarifying the timing of measurements. There is a recognition of the need to understand the graph's representation of data points at specific times, particularly around t = 12 hours.

Contextual Notes

Participants note that measurements appear to be taken at specific intervals (4, 8, 12, and 16 hours), which may influence their understanding of the limits and the function's behavior at those points.

Left- and right-handed limits.

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.
 
Forgot to post image...sorry. Please see top post.
 
Now that I can see the image, it looks like measurements are made just after 4, 8, 12, and 16 hours.
