The image asks to evaluate an expression, given the functions $f(x)$ and $g(x)$.

From the image:

• $f(x) = 3x - 4$
• $g(x) = 7 - x^2$

Please provide the specific expression you'd like to evaluate using these functions.

Would you like more details or explanations on these functions? Here are some related questions that can guide us further:

1. What is the value of $f(2)$ and $g(2)$?
2. How do you calculate $f(x) + g(x)$?
3. What is the domain of $g(x)$?
4. Can you solve for when $f(x) = g(x)$?
5. How do these functions behave when $x \to \infty$?

Tip: Always substitute values step by step when evaluating functions to avoid errors!
