To evaluate \( f(-4) \) for the function \( f(x) = 5x + 2 \), we substitute \(-4\) for \( x \) in the function:
\[
f(-4) = 5(-4) + 2
\]
Calculating this step-by-step:
1. Multiply \( 5 \) and \(-4\):
\[
5 \times -4 = -20
\]
2. Add \( 2 \) to \(-20\):
\[
-20 + 2 = -18
\]
Thus, \( f(-4) = -18 \).
The final answer is:
\[
\boxed{-18}
\]
\[
f(-4) = 5(-4) + 2
