Evaluate and interpret a restricted rational model
The modelled quantity is water volume; its input is elapsed time
In this situation, a water volume rises during a controlled fill
Let \(x\) be elapsed time, measured in minutes, and let \(y\) be water volume, measured in litres
The practical input condition is \(x\in[0,\infty)\)
\[y=119-\frac{288}{\left(x+2\right)^2}\]
Calculate y for the admissible input x=2
