The volume function is:
V= Length x Width x Height
We seek how to express each measure as a function of X4
[tex]\begin{gathered} \text{width = X} \\ \text{Length = 3X-2} \\ \text{Height = }4 \end{gathered}[/tex]
with clear measurments we can replace
[tex]V=(3x-2)\times(x)\times(4)[/tex]
we can reduce the expression to have a more similar to the options
[tex]V=(4x)\times(3x-2)[/tex]
I used V for Volume but in the options is Y however it is not a problem
[tex]Y=4x(3x-2)[/tex]
