The equation extracted from the image is:

$y = 6 - x^3, \quad \text{for } -3 \leq x \leq 2.5.$

How would you like to proceed with this? For example:

1. Should I calculate $y$ for specific values of $x$?
2. Should I generate a table of values for $x$ and $y$?
3. Would you like me to graph this function over the given interval?
4. Do you want me to analyze key points (e.g., maximum, minimum, inflection points)?
5. Any other calculations or interpretations you have in mind?

Let me know how I can assist! Here's one tip: always consider testing boundary points like $x = -3$ and $x = 2.5$ to better understand the range of the function.
