To compute $(f - g)(x)$, you need to subtract the function $g(x)$ from the function $f(x)$. This is done by subtracting the corresponding expressions or values of $f(x)$ and $g(x)$.

The formula is:

$(f - g)(x) = f(x) - g(x)$

To provide a specific solution, I would need the expressions for $f(x)$ and $g(x)$. If you have those, please provide them, and I can compute $(f - g)(x)$ for you.

Would you like more details or have any questions?

Here are some related questions:

1. What is the result of $(f + g)(x)$?
2. How do you compute $(f \cdot g)(x)$?
3. What is the derivative of $(f - g)(x)$?
4. How do you find the integral of $(f - g)(x)$?
5. How do you compute $(f/g)(x)$ when $g(x)$ is not zero?

Tip: Always check the domain of the functions involved to ensure that the operations are defined for all values of $x$.
