To solve $(f + g)(1)$, you need to evaluate the sum of the two functions $f(x)$ and $g(x)$ at $x = 1$. In other words:

$(f + g)(1) = f(1) + g(1)$

Do you have the specific definitions of the functions $f(x)$ and $g(x)$? Once you provide them, I can calculate the result.

Would you like to provide the functions for $f(x)$ and $g(x)$, or have more details?

Here are 5 related questions:

1. What are $f(x)$ and $g(x)$ defined as in this case?
2. How do you add two functions in general?
3. Can you apply this concept for different values of $x$?
4. What happens when $f(x)$ or $g(x)$ is a constant?
5. How do you graph the sum of two functions?

Tip: When combining functions, always calculate each function at the specific value first before adding them.
