The correct answer is the first one because:
1. x could be any number, it does not affect the function itself;
2, y approaches 0 since when x is infinitely big negative number (goes to negative infinity), [tex] \sqrt[3]{108} ^{2x} -\ \textgreater \ 0[/tex]
However, since it will never reach 0, y never could be 0 as well.
So, the correct answer is The First One.
