To find $f(7)$ for the function $f(x) = x + 2$:

$f(7) = 7 + 2 = 9$

Thus, $f(7) = 9$.

If you have any questions or need further details, feel free to ask! Here are some related questions you might consider:

1. What would $f(0)$ equal?
2. How would the function change if it was $f(x) = 2x + 1$?
3. Can you graph the function $f(x) = x + 2$?
4. What is the inverse function of $f(x)$?
5. How do you find $f(a)$ for any real number $a$?

Tip: Always check the function's definition before substituting values!
