Answer:
a. The value of A₀ changes from 10 to 20
b. t is replaced by (t-5)
Explanation:
a. The given formula comes with a description that says A₀ is the initial dose in mg. If the initial dose changes from 10 mg to 20 mg, then A₀ changes from 10 to 20. The function becomes ...
A = 20·0.97^t
__
b. Shifting the graph of the function to the right by 5 minutes is accomplished by replacing t with (t-5). At the same time, the domain changes from t ≥ 0 to t ≥ 5. The function becomes ...
A = A₀·0.97^(t-5) . . . . . . . . for t ≥ 5
