To solve problem 9(c), we need to evaluate the following limit:

\[
\lim_{{x \to 3}} (1 - 4x)
\]

### Solution
1. **Substitute \( x = 3 \) into the expression**:
   \[
   1 - 4 \cdot 3 = 1 - 12 = -11
   \]

Thus, the limit is:

\[
\lim_{{x \to 3}} (1 - 4x) = -11
\]

### Final Answer
The answer is:
\[
\boxed{-11}
\]
