Answer:
Domain: all real numbers, or (-oo, oo)
Range: (3, oo).
Step-by-step explanation:
The domain is the set of x-values that work when plugged into a function. Here, all values when plugged in produce a real answer, so the answer is all real numbers, or (-oo, oo).
The range is the result of the domain, or the y-values. Since the x^2 will only produce positive numbers, the lowest y-value we can get is 3, and the highest y-value we can get is infinity. So, the answer is (3, oo).

2 cups flour, 2/3 cups sugar, 1 1/3 cup of chocolate chips
Notice that 72 hours is 12 times the half-life of 6 hours. So, the starting amount of 100 mg will decay to half, 12 times. In other words
• after 1 hour, 100 mg decays to 50 mg
• after a total 2 hours, 100 mg decays to 25 mg
• after a total 3 hours, 100 mg decays to 12.5 mg
and so on, so that after a total of 72 hours, the hospital is left with
![\dfrac{100\,\rm mg}{2^{12}} = \boxed{0.0244140625 \, \mathrm{mg}}](https://tex.z-dn.net/?f=%5Cdfrac%7B100%5C%2C%5Crm%20mg%7D%7B2%5E%7B12%7D%7D%20%3D%20%5Cboxed%7B0.0244140625%20%5C%2C%20%5Cmathrm%7Bmg%7D%7D)
