To find $f(2)$ for the function $f(x) = x^2 + 5$, follow these steps:

1. Substitute $x = 2$ into the function: $f(2) = (2)^2 + 5$

2. Simplify: $f(2) = 4 + 5 = 9$

So, $f(2) = 9$.

Here are 5 related questions to expand on this concept:

1. What is $f(3)$ for the same function?
2. How do you find $f(x)$ for a general quadratic function?
3. How would the function change if the equation were $f(x) = x^2 - 5$?
4. Can you find the vertex of the function $f(x) = x^2 + 5$?
5. How does the graph of $f(x) = x^2 + 5$ compare to $f(x) = x^2$?

Tip: Always substitute the given value directly into the function and simplify step-by-step for clarity.
