![g(x)=[x] -1](https://tex.z-dn.net/?f=g%28x%29%3D%5Bx%5D%20-1)
is an example of a greatest integer function.
The greatest integer function takes in a real number and gives out the greatest integer that is less than that number.
So the domain of g(x) is all real numbers
<b> Any real value you plug in to the above function will be defined </b>
Answer:
The high of the water is<u> 2 cm.</u>
Step-by-step explanation:
The equation of this volume is:
![V=45*10*x](https://tex.z-dn.net/?f=V%3D45%2A10%2Ax)
We know that the volume is 900 cm³. So we just need to put this value in the above equation and solve it for x, which is the height.
![900=45*10*x](https://tex.z-dn.net/?f=900%3D45%2A10%2Ax)
![900=450*x](https://tex.z-dn.net/?f=900%3D450%2Ax)
![x=\frac{900}{450}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B900%7D%7B450%7D)
![x=2\: cm](https://tex.z-dn.net/?f=x%3D2%5C%3A%20cm)
Therefore, the <u>high of the water is 2 cm.</u>
