Answer: D. The number of times the drug has removed a certain percentage of fluid from the patient's lungs

Step-by-step explanation:

In a standard exponential function Ab^x, A is the initial amount and b is the multiplicative factor and x is the number of time periods.

Given: A medical lab is testing a drug that removes a certain percent of fluid from the lungs of a patient every eight hours.

The expression below represents the number of milligrams of fluid remaining in a patient's lungs after n days.

4.000(0.58)^3n,

As comparing to the standard exponential equation,  here 3n represents the number of times the drug has removed a certain percentage of fluid from the patient's lungs.

poizon [28]

It is the graph of f(x) = x^2 vertically compressed, and then translated 3 units up and 5 units to the right.

<h3>Transformation techniques</h3>

Transformation is a process of changing the size and shape of an object. The given graph is a graph of quadratic function with parent function x².

According to the graph shown the resulting parent function has been shifted horizontally to the right by 5 units to produce g(x) = f(x) - 5
