The true statements are:
- The practical domain of the function is [0,8)
- The amount of blood decreases at interval [0,8)
- The maximum amount of blood is 200
The equation of the function is given as:
[tex]A(t) = 200e^{-t}[/tex]
(a) The practical domain of the function
This is the value of t that makes sense for function A(t).
To do this, we plot the graph of A(t) (see attachment).
From the attached graph, the values of t that make sense are: 0 to approximately 8
Hence, the practical domain of the function is [0,8)
(b) The graph of the function
See attachment for the graph
(c) Increasing and decreasing intervals
At no interval does the amount of blood increase.
However, from the graph, the amount of blood decreases at interval [0,8)
(d) The maximum amount of blood
This is the vertex (maximum value) of the function
This is the initial value of the function.
Hence, the maximum amount of blood is 200
