It seems like the function $g(x)$ is not fully defined. To evaluate $g(2)$, I need to know the expression for $g(x)$.

If you provide the formula for $g(x)$, I can help you calculate $g(2)$. Could you please share that?

Here are 5 questions related to evaluating functions:

1. What is the general form of the function $g(x)$?
2. How do you evaluate functions at specific points?
3. Can you evaluate $g(x)$ for multiple values?
4. How can functions be used to model real-world scenarios?
5. What are the differences between linear and non-linear functions?

Tip: When evaluating a function, substitute the given value directly into the expression and simplify.
