<h3>
The complete exercise is attached.</h3>
You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:

Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:

Finally, evaluating, you get that the volume of the box is:

For this case we have the following equation:

From here, we clear the value of x.
We have then:

Then, we look for the value of 2x. We have then:

Answer:
The value of 2x is given by:

F(x) = 3x ; where x is the number of books purchased.
x f(x)
0 0
1 3
2 6
3 9
4 12
5 15
I saw this problem and the instruction was to graph the function and show the domain and range.
The domain is all the x-values while the range is all the y-values.
Answer:
domain: All real numbers
Range: all real numbers greater than or equal to 0
