Answer:
- 0 ≤ h
- The only asymptote in the domain is the horizontal asymptote c = 0.
- The only intercept in the domain is (x, y) = (0, 0).
- Maximum concentration occurs at h ≈ 1.95.
- About 1:33 pm
Step-by-step explanation:
1. For functions involving time, it usually makes no sense to evaluate them for negative values of time. At some point in the future, the value of the function is sufficiently small as to be "don't care", so that value of time is a good upper limit on the domain. Here, that might be about 100 hours, where the concentration is about 0.02%.
A reasonable domain might be 0 ≤ h ≤ 100.

2. In the domain, the only asymptote is horizontal. As h gets large, the value of the function becomes 2/h, so approaches zero.
The horizontal asymptote is C=0.
__
3. The only intercept is the origin, where C(0) = 0.
__
4. A graph shows the function maximum occurs at about h = 1.95.
__
5. A graph shows the value of C(5.544) ≈ 0.5. If we assume that C(h) represents the concentration in %, then the next injection should be given about 5.544 hours after 8 am, or at 1:33 pm. (My calculator converts hours to hours:minutes, so there is no "work" to show.)
