The problem asks to find an expression for an indicated function based on the given functions. However, the type of function operation (addition, subtraction, multiplication, etc.) is not clearly stated in the image. Let's first rewrite the given functions:

• $f(x) = 3x - 1$
• $g(x) = -3x^2$
• $h(x) = 4 + x^2$

Could you clarify what combination of the functions $f(x)$, $g(x)$, and $h(x)$ is required? Are we adding, multiplying, or performing another operation on these functions?

Once clarified, I will proceed with solving the problem.
