The function given is \( f(x) = -4 + 3 \). This simplifies to \( f(x) = -1 \), meaning that for any input \( x \), the output is always \(-1\).

Now, you are asked to find \( 3f(a) \):

\[
3f(a) = 3 \times f(a) = 3 \times (-1) = -3
\]

So, \( 3f(a) = -3 \).

Here are 5 related questions:
1. What would \( f(x) = -4 + 3x \) look like, and how would it affect \( 3f(a) \)?
2. How do we evaluate a function at a given value?
3. What happens if we multiply a constant function by another constant?
4. How does the graph of \( f(x) = -1 \) appear on a coordinate plane?
5. What is the general form of a linear function?

**Tip:** When dealing with constant functions, remember that the output remains the same regardless of the input value.
