The equation provided in the image is:

$x = \frac{y^3 - 1}{y^3 + 1}$

Would you like me to analyze this expression further? For example, I can simplify it, find limits, or explore any particular properties of this equation.

Here are five possible follow-up questions:

1. Would you like to simplify $\frac{y^3 - 1}{y^3 + 1}$?
2. Do you need to find the domain or range of this function?
3. Are there any specific values of $y$ you would like to evaluate?
4. Would you like to know if there are any asymptotes or special points for this function?
5. Do you need help graphing this equation?

Tip: When simplifying expressions, look for common factors that might cancel out, such as differences of cubes in this case.
