Answer:
![\text{ odd}](https://img.qammunity.org/2023/formulas/mathematics/college/a4cl96oernyqllalx6iiv0pwd6e4idun7d.png)
Step-by-step explanation:
Here, we want to check if the given function is even or odd
To do that, we find g(x) and g(-x)
If g(x) equals g(-x), the the function is even. Otherwise, the function is odd
We find the functions as follows:
![\begin{gathered} g(x)=7x^3\text{ - x} \\ g(-x)=7(-x)^3-(-x) \\ g(-x)=-7x^3\text{ + x} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/puw86ni3vbw4tp87qs5tdxpcbyp8vzpr22.png)
Finally:
![\begin{gathered} \text{ since g(x) }\\e\text{ g(-x) } \\ \text{Function g(x) is odd} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/p3tz3kk4uih0un7w7jo34htnywiw7kdmcb.png)
