1. The problem asks for the value of $f(x)3$, which is ambiguous but likely means $f(x) \cdot 3$ or $f(3)$ depending on context. 2. If $f(x)$ is a function, $f(x)3$ usually means $3 \times f(x)$, which is just multiplying the function value by 3. 3. Without a specific function $f(x)$ given, we cannot compute a numeric value. 4. If you meant $f(3)$, you need to provide the function $f(x)$ to evaluate it at $x=3$. 5. Please provide the function $f(x)$ or clarify the question for a precise answer.
