To evaluate \( f(-4) \) for the function \( f(x) = 5x + 2 \), we substitute \(-4\) for \(x\):
\[
f(-4) = 5(-4) + 2
\]
Calculating this step-by-step:
1. Multiply \(5\) by \(-4\):
\[
5 \times -4 = -20
\]
2. Now add \(2\):
\[
-20 + 2 = -18
\]
Thus,
\[
f(-4) = -18
\]
The correct answer is \(-18\).
\[
f(-4) = 5(-4) + 2
